.@byjacobward's assessment of where the AI race stands between China and the US: "The United States remains ahead in the sort of essential benchmarks. But whereas once upon a time we could have imagined that, you know, we were, let's say, a year, maybe two years ahead, now it's a matter of months."

FLASHBACK: Trump once said that if Xi Jinping visited the US, he would feed him a Big Mac instead of a state dinner.  W/ @PeterMeijer @secupp  @adrienneelrod & Cari Champion

"That was the biggest BS." @RepRobertGarcia reacts to the White House's "national security" argument for its press ban & triumphal arch plans.

Fmr. GOP Rep. @PeterMeijer scratches his head over what the White House gained from its media ban: "I cannot find a silver lining here."

The judge in the WH press ban case did not rule from the bench today and is promising to respond as soon as possible. @eliehonig @kpolantz & @brianstelter lay out what we could expect next. ⬇️

WATCH: @kasie explains the job of the press, the stakes involved, and why it must be free from government influence.

Trump today said that he will either reach a deal with Iran after the midterm elections, or "annihilate" the country. The top Democrat on the House Armed Services Committee, @RepAdamSmith, says that position is not "based in reality": "He doesn't outline what annihilate means. And clearly we don't have the capability of doing that."

.@marctshort on the GOP's midterm spending blitz: "I think it's hard to change the narrative at this point. I'm not as convinced that the money matters the way it used to."  W/ @davidaxelrod @LACaldwellDC @DavidChalian

"This is not good ball control for him," GOP Strategist @BradOnMessage says of Trump's move to ban CNN, Politico, and MS NOW from the White House. "I think he's really got to resist the temptation to take actions that make independents think he's chaotic."

"A flagrant violation of the First Amendment," @RepAuchincloss says of Trump's move to ban CNN, Politico, and MS NOW from the White House, adding that Fox News and all others should "boycott in solidarity."

As Trump says he's banning CNN, Politico, and MS NOW from the White House, hear how former GOP President Ronald Reagan once talked about the free press. ⬇️ Presidential historian @TimNaftali notes that "every White House spins," but that "no president before this one has sought to control information in this manner."

"Oh, they're afraid," @JeffFlake says of his former Republican colleagues as the midterms approach. ⬇️
