The latest installment of the Twitter Files revealed the FBI’s desire for Twitter to rely on it to be the belly button of the U.S. government (USG). The first Twitter Files installment of 2023 revealed shared the events that led up to the intelligence community’s influence on Twitter. Following that installment, journalist Matt Taibbi released another, which revealed the Global Engagement Center’s (GEC) role.
Taibbi described the GEC as “a fledgling analytic/intelligence arms of the State Department,” and screenshots revealed how this new entity would go directly to the media. In one such instance, a report titled, Russian Disinformation Apparatus Taking Advantage of Coronavirus Concerns, was released, which wrecked a bit of havoc for Twitter.
1.THREAD: The Twitter Files
Twitter and the FBI “Belly Button” pic.twitter.com/nfOGQGlvUM— Matt Taibbi (@mtaibbi) January 3, 2023
Twitter’s then Trust and Safety head, Yoel Roth, pointed out the motives of Clemson’s Media Forensic Hub when it complained that Twitter hadn’t “made a Russia attribution” in some time.

Roth told researchers like Clemson that Twitter would be happy to work directly with them instead of the media. He was unsuccessful. Simultaneously, Twitter was trying to reduce the number of agencies that had access to Roth. Twitter’s then-policy director, Carlos Monje, pointed out that once Twitter gave these agencies, such as the Department of Homeland Security, access to Roth.
“If these folks are like House Homeland Committee and DHS, once we give them direct contact with Yoel, they will want to come back to him again and again,” Monje said.
Taibbi noted that the GEC report appeared to be based on DHS data that was circulated earlier that week. The data included accounts that followed two or more Chinese diplomatic accounts and ended up with a list “nearly 250,000” names long. The list included Canadian officials and a CNN account.

In an email, Roth said that the GEC attempted to insert itself into conversations Twitter had with several government agencies, including the FBI and DHS. The GEC began to agree to loop Twitter in before going public; however, the agency used a technique that trapped Twitter previously.
“The delta between when they share material and when they go to the press continues to be problematic,” a comms official wrote, adding that they primed the media to be “curios and inquisitive of this dynamic, too.”

This led to Twitter’s disputing a State Department claim that China coordinated coronavirus disinformation accounts. The FBI then informed Twitter that the GEC wanted to be included in their regular “industry call” between companies like Twitter and Facebook and the DHS and FBI. At first, Twitter didn’t want to go this route. Executives at Facebook and Google were united with Twitter in its opposition to the GEC’s inclusion.
“The GEC’s mandate for offensive IO to promote American interests. The relative lack of discretion and caution from senior GEC leadership in sharing reports/analysis based on shaky methodology. A limited track record of successful collaboration with industry.”
Roth noted that an actor such as GEC being introduced to a stable and trusted group of practitioners and experts, especially with the election heating up, posed major risks.

Roth added that another reason was that the DHS and FBI were “apolitical,” whereas the GEC was “political.”
“GEC has a track record of actively advancing specific ideological agendas (e.g., their work w/r/t Iran). We should not lose sight of this distinction,” Roth wrote.

The FBI argued for a compromise solution that would allow other U.S. government (USG) agencies to participate in the industry calls, with the FBI and DHS acting as sole conduits. When Roth reached out to FBI agent Elvis Chan with concerns, Chan reassured the Twitter executive that it would be a “one-way” channel and “State/GEC, NSA, and CIA have expressed interest in being allowed on in listen mode only.”
“We can give you everything we’re seeing from the FBI and USIC agencies,” Chan told Roth, adding that the DHS agency Cybersecurity and Infrastructure Security Agency (CISA) “will know what’s going on in each state.” Chan then asked if the industry could “rely on the FBI to be the belly button of the USG.”

The group eventually chose Signal due to its operational security. Following that, Twitter began taking requests from various government bodies starting with the Senate Intel Committee (SSCI), which needed reassurance that Twitter was taking FBI direction.
Twitter also received various requests from officials wanting individuals they didn’t like to be banned from the platform. In the screenshot below, the office for Democrat and House Intel Committee chief Adam Schiff asked Twitter to ban journalist Paul Sperry.

At the time, Twitter refused. However, Sperry was later suspended. “No, this isn’t feasible/we don’t do this,” Twitter replied.
Twitter honored many of the requests, including those from the GEC, to ban accounts the GEC identified as “GRU-controlled” and linked “to the Russian government.”
A former CIA staffer working at Twitter called the GEC requests “Our window on that is closing,” which meant that the days Twitter could say no to serious requests were over. In the Twitter Files that were released earlier today, Taibbi noted that in public, Twitter would remove content at its “sole discretion.”
Privately, the platform would “off-board” anything that was “identified by the U.S. intelligence community as state-sponsored entity conducting cyber-operations.” That was in 2017. By 2020, agencies were flooding Twitter with “identifications” or users that it wanted Twitter to remove.

Taibbi pointed out that some reports were only a paragraph long and that Twitter would be forwarded an Excel document without further explanation. Twitter was also warned about the publicity surrounding a book written by former Ukraine prosecutor Viktor Shokhin, who alleged “corruption by the U.S. government” – specifically by Joe Biden.
Screenshots reveal that by mere weeks before the 2020 election, Twitter was so confused by the multiple streams of incoming requests that staffers had to ask the FBI which was which.

Taibbi noted that this led to the situation described in an earlier Twitter Files release by Michael Shellenberger on December 19, 2022.
In that release, it was revealed that Twitter was paid $3,415,323. Taibbi noted that Twitter wasn’t just paid but underpaid for the amount of work it did for the government.

SpaceX’s Raptor engine family has steadily increased sea-level thrust while simultaneously reducing mass, turning iterative engineering gains into substantially higher performance for the Super Heavy booster. CEO Elon Musk shed more light on how powerful Raptor 4 will be, and it’s pretty crazy.
Raptor 1 delivered 185 metric tons of thrust at roughly 2,080 kilograms, while Raptor 2 raised that to 230 tons while cutting mass to about 1,630 kilograms. SpaceX data for Raptor 3 lists a target of 280 tons at 1,525 kilograms (with further reductions in associated vehicle hardware), while operational flight ratings have been cited near 250 tons.
This morning, Elon Musk stated that Raptor 4 is expected to reach 300 tons of sea-level thrust at roughly the same mass as Raptor 3. Across these versions, thrust has risen by more than 60 percent from the first engines while engine mass has fallen, producing a sharp improvement in thrust-to-weight ratio. This is a true testament to how great SpaceX engineering has been:
🚀 Elon says Raptor 4 will make 300 tons of thrust at sea level at roughly the same mass as Raptor 3.
How far Raptor has come:
Raptor 1: 185 tf, 2,080 kg
Raptor 2: 230 tf, 1,630 kg
Raptor 3: 250 tf, 1,525 kg
Raptor 4: 300 tf33 on Super Heavy = ~9,900 tf, nearly 3x Saturn V https://t.co/HQDswZhyvL

With 33 engines on SuperHeavy, the jump from earlier versions to a 300-ton Raptor 4 would produce roughly 9,900 metric tons of total liftoff thrust, nearly three times the Saturn V’s approximately 3,400 metric tons from its five F-1 engines.
This is not just a larger number on a data sheet, either, as sea-level thrust is the force available the moment the vehicle leaves the pad. This is when it is heaviest and still deep in Earth’s gravity well and dense atmosphere.
Higher levels of sea-level thrust directly improves the initial thrust-to-weight ratio of the full stack. A higher ratio produces faster acceleration off the pad, which shortens the time the rocket has to spend fighting gravity, and gravity losses during the first minute or two of the flight are a major drain on total available delta-v. Every second shaved off of that early climb preserves more propellant energy for reaching orbital velocity or for carrying extra payload.
Because Super Heavy’s engine count is constrained by vehicle diameter and packing density, increasing thrust per engine is the most straightforward way to raise total liftoff performance without redesigning the booster structure or design.
The same-mass target for Raptor 4 is equally important. Holding engine mass roughly constant while raising thrust improves the engine’s own thrust-to-weight ratio and reduces the structural and propellant mass fraction that must be carried solely to support the engines.
Earlier Raptor iterations also simplified or eliminated extensive vehicle-side hardware such as heat shields. These gains compound: more force for less installed mass leaves additional capacity for propellant, payload, or operational margins such as engine-out capability.
For Starship’s architecture, the practical effects are large. Greater liftoff thrust supports heavier vehicles, larger propellant loads, and higher payloads to low Earth orbit, figures SpaceX has targeted in the 100-plus-ton reusable range. That capacity underpins orbital refueling, lunar missions, and eventual Mars cargo and crew flights.
Continued growth in sea-level thrust therefore tightens the gap between theoretical rocket performance and the high flight rates and reusability needed to make large-scale space transport practical.
Tesla has expanded its Tesla Assisted Driving (TAD) suite to its tenth European country, as Latvia joined a growing list of European Union member states authorizing the company’s advanced driver assistance technology.
Tesla Europe announced this morning that the system is now approved in Latvia, with a software rollout to begin soon.
The approval and rollout follow recognition of a provisional European type approval originally granted by the Netherlands’ RDW authority on April 10.
🚨 Latvia has just received approval for Tesla Full Self-Driving (Supervised)
This is the 10th country in the EU to gain approval:
1. Netherlands — 10 April 2026 (original RDW approval)
2. Lithuania — 20 May 2026
3. Estonia — 29 May 2026
4. Denmark — 9 June 2026
5. Belgium — 10 June 2026
6. Slovenia — 7 September 2026
7. Czechia — 21 September 2026
8. Croatia — 29 September 2026
9. Slovakia — 16 October 2026— TESLARATI (@Teslarati) October 26, 2026
Latvia’s Road Traffic Safety Directorate (CSDD) evaluated the Dutch documentation, coordinated with the other national authorities, and reviewed updates from Tesla. These included tightened limits on speed offsets, automatic resets of any manual speed adjustments after each trip, and stronger driver monitoring.
In Europe, the feature is marketed as Tesla Assisted Driving after a recent rule change that labeled the name “Full Self-Driving” as misleading.
The system remains an SAE Level 2 driver assistance tool, not unsupervised autonomy. It can control speed, steering, braking, lane changes, and intersections while following a navigation route. Drivers need not keep their hands on the wheel at all times, yet they must continuously monitor the road and be prepared to intervene immediately.
The sequence of EU recognitions began with the Netherlands in April and continued through Lithuania, Estonia, Denmark, Belgium, Slovenia, Czechia, Croatia, and Slovakia. Most have relied on mutual recognition of the single Dutch provisional approval rather than independent national testing.
These national clearances do not yet constitute bloc-wide authorization. An EU-wide decision requires a qualified majority in the Technical Committee on Motor Vehicles: at least 15 of 27 member states representing 65 percent of the EU population. Larger markets, like Germany, France, and Italy, remain under review, and a vote is expected this December.
However, for Latvian Tesla owners with compatible vehicles and software, the imminent rollout expands access to the supervised system while underscoring that attentive human oversight remains essential.
Tesla expanded its Robotaxi geofence in Houston, Texas, today, enlarging the service area and drawing a new rocket-shaped boundary across the city’s northwestern and central parts.
Although CEO Elon Musk said it was just a coincidence, the expansion seems to be an ode to SpaceX and its potential merger with Tesla.
🚨 Tesla has just expanded its Robotaxi geofence in Houston
It looks a lot like a rocket — we all remember the shape in Austin 🤣 https://t.co/cFOPEuiJ4u
— TESLARATI (@Teslarati) October 26, 2026
The official Tesla Robotaxi account announced the change with the lines “Houston, we have liftoff” and “Bigger service area now live,” pairing them with a map overlay.
The prior white geofence, roughly 25 square miles covering Jersey Village, Harvest Bend, and the Willowbrook corridor along U.S. 290 and State Highway 249, now sits inside a larger blue zone that stretches southeast toward Bellair and closer to central Houston.
Houston’s Robotaxi service launched on April 18, 2026, the same day as Dallas, as Tesla’s first unsupervised public expansion beyond Austin. From the start, the vehicles were Model Ys running without anyone in the front seats, booked through the dedicated Tesla Robotaxi app and open to the public inside the geofence.
Trackers measured the initial zone at about 25 square miles; by late September it had not grown substantially. Community and registry data indicated a modest local fleet of unsupervised Model Ys, while dozens to nearly 200 Cybercabs, the purpose-built, steering-wheel-free two-seaters, have been spotted staging and testing in Houston lots, though public Cybercab rides remain limited to Austin for now.
Across the broader Robotaxi program, Tesla began public Robotaxi rides in Austin in June 2025, as a small geofence and vehicles with safety monitors became available for a ride-hailing service. Later on, Tesla removed the monitors and steadily expanded the service area until it covered most of the Austin metro area.
Unsupervised Robotaxi services now run in six cities: Austin, Dallas, Houston, Miami, Orlando, and Tampa. Cumulative driverless miles reported by the company have reached several million. The Cybercab entered public service in Austin in early September 2026 and has scaled rapidly there. The company has also said that Dallas is next for Cybercab rides in November, with further cities and 24/7 hours targeted by year-end, plus fleet-operator sales of the vehicle.
Waymo also operates a fully driverless service in Houston, which has been open to the public since August of this year.
The Houston expansion continues Tesla’s pattern of starting with tightly controlled validation zones before widening coverage as real-world data accumulates, while the rocket motif on the map underscores the company’s habit of injecting visual flair into its autonomy rollout.
Riders inside the new boundary can request unsupervised Model Y trips in the Robotaxi app; exact operating hours and further Cybercab availability remain subject to app updates and company statements.
