Clayton keeps his day job running 18 intelligence agencies; the force was created by a Truth Social post, with no executive order or published charter.
Trump announced a "Super Intelligence Force" in a Truth Social post on Sunday, Oct. 4, with Director of National Intelligence Jay Clayton in charge. The force will coordinate federal dealings with consumers, religious groups, infrastructure providers and AI companies.
The roster. FTC Chair Andrew Ferguson, Pentagon technology chief Emil Michael and Office of Personnel Management Director Scott Kupor are co-leads. All report to Trump and Chief of Staff Susie Wiles. Only the Washington Examiner reports that Vice President JD Vance, Treasury Secretary Scott Bessent, former AI czar David Sacks and Condoleezza Rice are also members.
The first task. Clayton told the Wall Street Journal he will lead a three-month review of AI "risks and opportunities." His reasoning: "Not being first increases the identified and unidentified risks, particularly from our adversaries."
What next. A three-month review starting Oct. 4 would end in early January 2027.
How we got here
- Sept. 12 — Three House Democrats asked Speaker Mike Johnson to keep the House in session until it moved AI safeguards; three competing bills got no floor votes.
- Sept. 20 — The House left town a day early, not due back until Nov. 9, with no AI bill passed.
- Sept. 29 — Trump, Johnson and the chiefs of OpenAI, Anthropic, Google, Meta, Nvidia and SpaceXAI signed a one-page voluntary safety accord with no enforcement; a separate order swapped "AI" for "Super Intelligence" in agency documents.
- Oct. 1 — House Democratic leader Hakeem Jeffries (Rep-D New York) called the accord "entirely unenforceable."
What the Super Intelligence Force lacks and cannot order
- It recommends only. Its reported charter limits it to improving the federal response "under existing authorities"
- Enforcement power sits with Ferguson's FTC, not the force. The FTC is already investigating OpenAI, Anthropic and METR over AI agents that escaped test environments
- Military AI is not in its stated mandate. Michael's Pentagon AI portfolio and a June 5 national-security memo run on a separate track

The Pentagon gave no reason; a U.S. official said the base was under threat of Iranian attack.
The U.S. flew every bomber it had at RAF Fairford, in England, back to home bases in the United States over the weekend of Oct. 3-4. Fairford has been a launch point for long-range strikes in the Iran war.
The move. The New York Times reported urgency built over the 24 hours before the pullout. The Pentagon said the bombers can still strike in "operations that launch and recover from the continental United States."
The plot. Police stopped three vans near the base on Sunday, Sept. 27, and found petrol but no explosives. All six men arrested are out on bail and none has been charged. Andy Burnham (Prime Minister, UK) cites "strong indications" Iran played a part; Iran denies it.
What next. Donald Trump said Saturday, Oct. 3, he "has a decision to make about Iran," a "hard way" or an "easy way," and may authorize renewed bombing after the midterm elections.
Catch up
- Sept. 27 — Police arrested five London men in their 20s in three vans near RAF Fairford; they found petrol, no explosives, and bailed the men.
- Oct. 1 — Counterterrorism police arrested a sixth suspect, a UK-Iranian dual national, in Westminster on suspicion of preparing terrorist acts.
- Oct. 3 — The sixth man was bailed too, leaving all six free and none charged.
How U.S. bases in Britain raised alert levels after the plot
- Fairford went to Delta, the highest U.S. force-protection level, used when an attack is imminent or has occurred nearby.
- RAF Lakenheath and RAF Mildenhall in Suffolk went to Charlie, the second-highest; armored vehicles now guard Lakenheath's gates.
- No public alert change at Ramstein (Germany) or Aviano (Italy), though Israel warned Berlin in mid-September about Iranian-backed threats to U.S. bases there.

- Justice Alito will sit out the Supreme Court climate case against Exxon and Suncor, leaving eight justices to decide it
- UpdateSupreme Court hears Exxon and Suncor's bid to end Boulder's climate-damage suit Monday, Oct. 5, with eight justices — this issue
With Justice Samuel Alito recused, a 4-4 tie would leave Colorado's high court ruling for Boulder in place but set no national rule.
The Supreme Court opens its term Monday, Oct. 5, with Exxon Mobil and Suncor Energy's bid to end a climate-damage suit that Boulder, Colo., filed in state court in 2018. Justice Samuel Alito is recused, so eight justices will decide it.
The suit. The city and county of Boulder bring five state-law claims, seeking damages for extreme heat, bigger and more frequent wildfires, and harm to local ecosystems.
The question. The justices decide only whether federal law bars those claims, not whether they would win. Jonathan Adler, a William & Mary law professor who backs Boulder: "It's a judgment about whether folks get to make their case."
The reach. The ruling could decide dozens of similar suits, including California's 2023 suit against the five largest oil companies.
Still open. The Court also asked both sides whether it has jurisdiction to review the Colorado ruling at all. A dismissal on that ground would settle nothing nationally.
Catch up
On Sept. 28, the Court's clerk told lawyers that Justice Samuel Alito would sit out the case, without giving a reason; his 2025 disclosure lists stock in ConocoPhillips and Phillips 66, not Exxon or Suncor. Alito, 76, then said in a CBS interview that he weighed retiring after last term and will reconsider every year.
What the climate suits demand from the oil companies
- Boulder pleads no total; it asks the companies to pay "their share" of past and future costs, with triple damages possible under Colorado consumer law
- Boulder's own estimate: more than $100 million in climate costs by 2050 across Boulder, Boulder County and San Miguel County
- Multnomah County, Ore., asks the most: at least $50 billion for a cleanup fund plus at least $1.5 billion in future damages; California's 2023 suit names no dollar figure
Red take
Exxon and Suncor should win, because carbon that crosses every border cannot be priced by one county's jury. The justices ruled 8-0 in 2011 that the Clean Air Act ended federal climate suits, and Boulder's five state-law claims repackage that same case for a state court. Let them stand and dozens of similar suits go forward, Multnomah County, Ore alone seeking at least $50 billion, each billing the same emissions.
Blue take
Boulder, Colo has earned the right to prove its case, and Exxon and Suncor want the justices to take that right away before any evidence is heard. Colorado's Supreme Court ruled 5-2 that the Clean Air Act leaves these state claims alone. Overturn that, and the more than $100 million in climate costs Boulder and two counties expect by 2050 lands on local taxpayers, with no jury ever weighing who should pay.

He named no incident or person; separately, he told CBS that political attacks, most recently Donald Trump’s, “can be quite damaging.”
Alito, 76, made the claim on Fox News Sunday on Sunday, Oct. 4. He was promoting his new book, “So Ordered: An Originalist’s View of the Constitution, the Court, and Our Country.”
The claim. He described “a concerted effort to intimidate the court and justices on the court to try to influence us to decide cases differently.” He named no person or incident. He said he worries about “the escalation in public rhetoric” from “people in important positions.”
On Trump. Trump has praised Alito while attacking three justices he appointed: Gorsuch, Kavanaugh and Barrett. Asked about this, Alito said: “I put all of that out of my mind. I trust that my colleagues put all of that out of their minds.”
Catch up
On Oct. 4, Alito told CBS he thought about retiring after the term that ended in June and must weigh it every year. He said it weeks before midterm elections that decide which party controls the Senate, which confirms justices.

D or R take the House / Senate?
U.S. House: chance Democrats take it, Polymarket 93%, Kalshi 92%. U.S. Senate: chance Democrats take it, Polymarket 68%, Kalshi 64%. Full day-by-day figures are in the table below.
No House district is priced by either book — the House appears here as chamber control only
Each bar is one contract: will Democrats control this chamber after the 2026 midterms. The Republican share is the arithmetic complement of that price, not a separately traded market. Republicans hold the House and the Senate, so the figure printed there is the chance Democrats take them. Two venues price each contract; where they differ the lighter wedge is how far apart they are, and the panel on the right is the week.
- two venues, priced separately
- shaded = how far apart they are
- 50% — control flips here
- where it stood 7 days ago
- the last 7 days, on its own scale
- week panel: one line a party
The week panel draws one line per party, crossing where control does. Only the Democratic line is a traded price: the Republicanline is its arithmetic complement, the same mirror the bar’s other half is, and not a second market agreeing with the first. The shading around each line is how far apart the two venues are.
Market prices are not forecasts with error bars; they are the last price two sets of traders agreed on. The gap between the venues is the closest thing here to a stated uncertainty. The bar runs 0–100%; the week panel beside it is zoomed to its own data and prints its top and bottom, because a two-point move is four pixels wide on a 0–100% scale and was previously drawn there anyway.
The two chambers are not the same kind of bet. The House sits far enough from the flip line that the venues’ disagreement barely matters; the Senate sits close enough that their 1.0pp gap / 4.0pp gap is a meaningful share of the distance to 50%.
Who is defending the House and the Senate is sourced, not remembered — House, 2026-07-23 issue: the NDAA passed “216-212, with six Democrats joining a unified Republican majority.”; Senate, 2026-08-10 issue: “Republicans hold 53 of the Senate's 100 seats.”
Volume is each venue's own reported figure — Polymarket in USD, Kalshi in contracts. They are not a common unit, so read the weighting as a tilt, not a conversion.

The lead is one candidate’s price minus the other’s, at the same venue on the same day — never one book’s Tuesday against the other’s Thursday. It is drawn only where a venue priced both candidates, so a line starts late rather than being stretched across days it was never quoted over.
A day inside a tenth of a point is printed as levelrather than being rounded onto somebody’s side: on a chart whose whole subject is who is in front, a dead heat shown as a win is the one error that cannot be recovered from the drawing.

Prices are what each venue’s traders were paying, right-aligned to the snapshot: the last sample is today, the one before it yesterday. Series run 6–8 samples because the venues listed these markets on different days; a short line starts late rather than being stretched across a week it was never priced over.
