Ukrainian President Volodymyr Zelensky told CNN on Saturday that he's "ready for [the] next call with Mr. Trump" if working with the U.S. and the president will help his country.

I visited my alma mater — Washington and Lee University in Lexington, Va. — this week for a sneak peek at Saturday's 27th running of a 112-year tradition: The nation's best known mock political convention.

Why it matters: The students treasure their record for accuracy, despite having to make the pick early in the primary process: In 26 previous conventions, W&L has correctly predicted the out-of-party nominee 20 times (including the year I was Western regional chair, and Sen. Joe Biden was our keynoter).

Former Deputy Attorney General Sally Yates accused President Trump of using the Justice Department "as a cudgel against his enemies and as a shield for himself and his allies" in a Washington Post op-ed Friday.

Why it matters: Yates served in the DOJ under President Obama and stayed on as a holdover as acting attorney general until she was fired less than two weeks into Trump's presidency for refusing to implement the president's travel ban.

Mandy Gunasekara, former deputy assistant administrator in the Environmental Protection Agency's air office, is expected to become the next chief of staff, the Washington Post reports.

The state of play: Avenatti, who has been in prison since allegedly violating his bail conditions last month, was convicted of attempted extortion, honest-services fraud and the related use of interstate communications. He could face more than 40 years in prison at his June 17 sentencing, but will likely receive less, per Reuters.

Attorney General Bill Barr has assigned an outside prosecutor to monitor the Justice Department's ongoing case against President Trump's former national security adviser Michael Flynn, the New York Times reports.

Facebook said Friday that political candidates, campaigns and groups can use paid branded content across its platforms, a clarification prompted by a move from Michael Bloomberg's campaign to pay top Instagram influencers to post memes on its behalf.

Bernie Sanders has risen to the top of the Democrats’ 2020 pack on the appeal of his far-left idealism and promises of a “revolution” — but he’ll have a hard time turning revolution into reality if he gets the chance.

The big picture: Even with the expanding power of the presidency, Sanders would need Congress to approve the most ambitious ideas he’s known for — and that’s unlikely to happen even under the strongest elections scenarios for House and Senate Democrats in November.

Here’s a look at the odds for 10 of Bernie Sanders’ most ambitious proposals, according to Democratic aides, outside experts and Axios’ issue experts.
