In the words of Seth Meyers, President Donald Trump has “completely lost his mind” over the FBI’s raid of his lawyer Michael Cohen’s office.

“It’s hard to imagine how Donald Trump could be in more legal jeopardy than he is right now,” the Late Night host said at the top of a nearly 10-minute segment on the latest setback for the president.

After recapping just how the FBI—on a tip from Robert Mueller’s Russia investigation—came to seize documents related to the Stormy Daniels hush payment from Cohen’s office, Meyers said, “This is like the series finale of a TV show where they try to tie all the different plot points together.”

“If Trump ever goes on trial, they’re going to call characters from previous episodes into the courtroom like the last episode of Seinfeld,” he added, imagining Trump asking, “‘Oh no, Anthony Scaramucci, what did I do to you?!’”

“Of course, when news like this breaks, we can always count on our calm, rational president to react in a measured way,” Meyers said before reading Trump’s unhinged tweets from Tuesday morning.

“What is Trump’s strategy here?” he asked. “To act so guilty the Feds will think he has to be innocent? You know, the insanity defense only works after you’ve been arrested, right?”

The host went on to point out how Trump “immediately threw” Cohen “under the bus” just before the raid occurred when he denied knowledge of the Stormy Daniels payment, saying, “You’ll have to ask Michael Cohen.”

“That’s right, he said, ‘Ask Michael Cohen’ and it looks like the FBI said, ‘OK,’” Meyers said.

“Michael Cohen was very much the keeper of Donald Trump’s most closely-held secrets and the fact that the FBI raided his office to seize his communications with Trump is being taken by outside lawyers as a sign of just how serious the investigation is,” Meyers added later. “Cohen may very well know more about Trump than any other human being on the planet.” That might explain, he said, why Trump seemed to become “totally unglued” when he started “attacking the FBI” during a meeting on Monday that was supposed to be about Syria, calling the raid a “disgrace” over and over again.

“Hey man, if you’re not going to bother to read the Constitution, can you at least check out a thesaurus?” Meyers asked. “This is one of the most consequential and potentially most perilous moments of the Trump presidency. One of his closest confidants is in the cross-hairs of the FBI and he’s openly threatening to shut down the special counsel’s investigation.”

If that happens, Meyers said he can think of one word he would use to describe the situation: “Disgraceful.”
