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.

With the interview tour that began Sunday night on ABC, fired FBI director James Comey is forcing those in and out of power to take sides.

“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.

Comey is not merely a fired employee who thinks Trump is a flawed man. He is also a potential witness, and Comey – and surely special counsel Robert Mueller – know this well.

“If Bob Mueller is let — left in place to do his job, he will find the truth,” Comey said.

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.

Then there’s the continued speculation about whether Deputy Attorney General Rod Rosenstein and, ultimately, special counsel Robert Mueller, will keep their jobs. Legislation is working its way through both chambers to protect the men.

And, finally, Mike Pompeo is expected to answer more questions from senators as lawmakers prepare to vote on his nomination to be Trump's secretary of state. GOP Sen. Rand Paul is a no vote, which means the administration will need not only all the other Republicans but at least one Democrat on the Senate Foreign Relations Committee to give him a favorable recommendation for a floor vote.

The TIP with Matt Seyler

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

She issued a statement saying "I have never hesitated to make the hard decisions, guided by the Department of Justice’s core principles of integrity, independence and above all, always doing the right thing. The Justice Department’s handling of the Clinton email investigation under my leadership was no exception."

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.

"Throughout his time as Director we spoke regularly about some of the most sensitive issues in law enforcement and national security. If he had any concerns regarding the email investigation, classified or not, he had ample opportunities to raise them with me both privately and in meetings. He never did.”
