Mark Sandy, a White House official working in the Office of Management and Budget, will testify in the impeachment inquiry if served with a subpoena by House investigators, his lawyer Barbara Van Gelder told the Washington Post Thursday.

Why it matters: Sandy would be the first OMB employee to break the White House's blanket non-cooperation policy and could shed light on the motivation behind the Trump administration's decision to freeze nearly $400 million in military aid to Ukraine.

  • Unlike OMB acting director Russell Vought and other political appointees in the White House, several of whom have defied congressional subpoenas, Sandy is a career official.
  • The Post reports that he was one of the White House staffers who raised questions about the aid freeze and that he was at one point responsible for signing documents that prevented the funds from going to Ukraine.

Between the lines: Why President Trump froze the security assistance and why he ultimately decided to release it are two of the fundamental questions at the heart of the probe into his alleged efforts to pressure Ukraine to investigate his political rivals.

  • Republicans have criticized the witnesses called by Democrats, including diplomats Bill Taylor and George Kent, for not having firsthand knowledge of Trump's thinking and the events that took place. Sandy could poke a hole in that defense.

Confidants of Joe Biden believe his choices for vice president have narrowed to Sen. Kamala Harris and Susan Rice — and would be surprised if he picks anyone else.

The coronavirus will make the 2020 presidential election different from any in modern history: Voting that begins earlier, results that take longer, mail carriers as virtual poll workers and October Surprises that pop in September.

The big picture: Perhaps 80 million Americans will vote early, by mail or in person, Tom Bonier, CEO of TargetSmart, a Democratic political data firm, tells Axios. That's going to set up more of an Election Season than an Election Day — and increase the odds of national turmoil over the vote count.

Driving the news: McCarthy delivered a PowerPoint presentation to the GOP conference in person last Thursday at the Capitol Visitor Center, with several members joining via Zoom, lawmakers and aides familiar with the gathering tell Axios.
