Sen. Tommy Tuberville revealed late Wednesday that he spoke to Donald Trump on Jan. 6, just as a violent mob closed in on the the Senate, and informed the then-president directly that Vice President Mike Pence had just been evacuated from the chamber.

“I said ‘Mr. President, they just took the vice president out, I’ve got to go,’” Tuberville (R-Ala.) told reporters on Capitol Hill on Wednesday night, saying he cut the phone call short amid the chaos.

The existence of the phone call had been previously reported, but the detail that Tuberville informed Trump his vice president was in danger is a new and potentially significant development for House prosecutors seeking Trump’s conviction: it occurred just around the time that Trump sent a tweet attacking Pence for not having “the courage” to unilaterally stop Joe Biden’s victory. And Trump never indicated publicly that he was aware of Pence’s plight, even hours after Tuberville says he told him.
