President Trump's former Russia adviser Fiona Hill arrived on Capitol Hill to testify in the House's Ukraine investigation Monday after receiving a subpoena from the Democratic-led committees leading the impeachment inquiry, her attorney confirmed on Twitter.

Why it matters: Hill, who left her role as Trump's top Russia aide in August, is expected to testify that Trump's lawyer Rudy Giuliani and U.S. Ambassador to the EU Gordon Sondland "circumvented [the administration] to pursue a shadow foreign policy on Ukraine," according to NBC News. That policy included pushing Ukraine to open investigations into the 2016 presidential election and unsubstantiated corruption allegations against Joe Biden and his son.

The Democratic chairs of the House Oversight and House Foreign Affairs committees announced subpoenas Monday for four State Department officials as part of their investigation into the firing of former Inspector General Steve Linick.

Why it matters: The two committees, in addition to Democrats on the Senate Foreign Relations Committee, are investigating whether Linick was fired because he was probing Secretary of State Mike Pompeo and the State Department's attempts to bypass Congress to sell weapons to Saudi Arabia and the United Arab Emirates.

Pelosi: Birx "enabled" Trump on coronavirus misinformation

House Speaker Nancy Pelosi told CNN on Monday she does not have confidence in White House coronavirus task force coordinator Deborah Birx because "she has enabled" President Trump to spread coronavirus misinformation.

What she's saying: "I don't have confidence in anyone who stands there while the president says, 'Swallow Lysol and it's going to cure your virus,'" Pelosi told host Jim Sciutto.
