Good Tuesday morning. I am Jake Sherman and welcome to your Politico Playbook Flash Briefing,

brought to you by the Better Medicare Alliance. And I'm Anna Palmer. 963 days. That's how long

an average national security advisor lasts. Michael Flynn resigned last night, making his tenure 24 days.

Trump last night named Lieutenant General Joseph Kellogg as

acting national security advisor. It was the end to a traumatic few days for the Trump White House,

where all a professional Washington was watching Flynn's fate closely. Here's what you need to know.

In his resignation letter, Flynn admitted to giving incomplete information to Vice President Mike Pence about his calls with the Russian ambassador.

Flynn's replacement, Kellogg, is unlikely to be a long-term replacement.

The New York Times is also reporting that Flynn loyalist Katie McFarland is expected to leave the administration.

Retired Vice Admiral Robert Harwood is already

being floated as the lead candidate to replace Flynn. Meanwhile, David Petraeus is also in the mix.

I spent a bunch of time on Capitol Hill yesterday and saw how Mike Penn spent his time just

hours before Flynn tendered his resignation. The vice president was meeting with groups of lawmakers all

over the Capitol, was walking around with a massive entourage and a massive security detail,

talking about things like health care and tax reform. Pence did not answer questions about Flynn from

reporters, but he really didn't seem flustered, upset, or angry. He glided past the Speaker's

lobby, the room that runs the distance of the

House floor where we used to chat with Mike Pence all the time. He stopped for Texas Congressman

Sam Johnson, a veteran House Republican who was sitting just outside the House floor. One fun fact,

during the House vote, Pence was in the House Republican cloakroom, a hangout restricted to members

of Congress where he was making peanut butter and

jelly sandwiches. See Playbook in your inbox or online for a photo. We've got lots of scoops this
