Stephen Colbert fires away at Trump: 'You're a bad president. Please resign.'

Stephen Colbert called for President Donald Trump to step down after a report said Trump revealed highly classified information to Russian diplomats.

"The good news? Trump found the leaker," Colbert said during the opening monologue of Monday's "Late Show" of the president's search for those who have leaked information to the media.

On Monday, The Washington Post reported that Trump last week revealed classified information about an "Islamic State terrorist threat" while meeting with the Russian foreign minister and ambassador.

White House officials have since pushed back on the report. Secretary of State Rex Tillerson said in a statement: "During that exchange, the nature of specific threats were discussed, but they did not discuss sources, methods, or military operations."

Meanwhile, the reaction to the reported sharing of classified information has been swift and harsh. Alan Dershowitz, a legal expert, said it was "the most serious charge ever made against a sitting president."

One US official told The Post that the leaked details were considered "code-word information."

In an effort to explain to his audience what that means, Colbert offered some examples: "The package has been delivered. The squirrel is in the basket. The idiot is in the Oval. It could mean anything. We don't know what that means."

Colbert then pivoted to the ongoing controversy surrounding the president's firing of FBI Director James Comey. The host focused on Trump's recent tweet, a vague threat suggesting he would release tapes of conversations he had with Comey if he leaked anything to the media.

"That would be huge. It would be the first time a leaked tape made Donald Trump look good," Colbert said, alluding to the video that leaked before the 2016 election showing Trump boasting lewdly about making aggressive sexual advances toward women.

Amid the fallout over Comey, Trump has reportedly been unhappy with his staff and considering replacing key members in what has been called a "reboot." But Colbert made a plea to keep White House press secretary Sean Spicer, a frequent source of entertainment for the host.

"I have something to say here. Donald Trump, if you're watching, first of all: You're a bad president. Please resign," Colbert said. "Second: Please, please, please don't take Sean Spicer from us! Where am I going to get my daily dose of veiled anger and condescension?"
