The Note: Comey and Trump raise the stakes

This "slime ball" gets his say, and then some.

The TAKE with Rick Klein

This “slime ball” gets his say, and then some.

That enrages President Donald Trump, based on his tweets. And it may mean much more than name-calling and anger before it’s through.

“He is morally unfit to be president,” Comey told George Stephanopoulos.

Trump’s early counter to Comey’s book, that Comey should be behind bars, only raises the stakes in this highest-dollar kind of game.

Trump brags about being a counter-puncher, so Comey stands warned. But this fight could have far deeper costs, depending on how the coming days play out.

The RUNDOWN with Emily Goodin

It will be a busy week of back and forth between Congress and President Trump.

First off - any reaction to James Comey's interview on ABC, particularly his comments on when the investigation began into Russian election interference, his Oval Office meeting with Trump on Michael Flynn, and whether the Russians have something on the president.

On Syria, a chorus of Democrats – and at least one Republican – have questioned whether the military action is on questionable legal ground because the legislation Trump relied on to use force without congressional authorization has not been updated since 2001.

The TIP with Matt Seyler

Just before the ABC interview - strong pushback to James Comey from former Attorney General Loretta Lynch.

Lynch continued, "at the critical early stages of this case, I followed the Department’s long-standing policy of neither confirming nor denying the fact of an ongoing investigation. " It neither misleads nor misinforms, but instead both protects investigations and guarantees equal treatment of those under scrutiny, whether well-known or unknown. Any suggestion that I invoked this bedrock policy for any other reason is simply false.”

She concluded by noting she has known Comey for almost 30 years.

QUOTE OF THE DAY

He would have fired me on the spot." - Former New Jersey GOP governor Chris Christie on "This Week" responding to the James Comey interview.
