Michigan Rep. Justin Amash (L) is no longer campaigning for public office, including his House seat, an aide told the Detroit News.

Why it matters: Amash is the first member of the Libertarian Party to serve in Congress. He left the Republican Party in 2019, and has served in Congress since 2011. He has also been a vocal critic of President Trump and partisanship in Washington, D.C.

What they're saying: "He hasn't been campaigning for any office and doesn't plan to seek the nomination for any office," Amash adviser Poppy Nelson told the Detroit News.

The big picture: After Amash announced that he will not run as a candidate in the 2020 presidential race in May, the Libertarian Party hoped he would seek the nomination for his House seat.

Marc Short, Vice President Mike Pence’s chief of staff, tested positive for the coronavirus Saturday and is quarantining, according to a White House statement.

Why it matters: Short is Pence's closest aide, and was one of the most powerful forces on the White House coronavirus task force. Pence and second lady Karen Pence tested negative for the virus on Sunday morning, according to the vice president's office.

AOC: "Extremely important" that Biden offer Bernie Sanders a Cabinet position

Rep. Alexandria Ocasio-Cortez (D-N.Y.) said on CNN's "State of the Union" Sunday that she believes it's "extremely important" that Joe Biden offer Sen. Bernie Sanders and other progressive leaders Cabinet positions if he's elected president.

The big picture: Ocasio-Cortez was pressed repeatedly on policy differences between her and the more moderate Biden, including her opposition to fracking and support for Medicare for All. She responded that it would be a "privilege" and a "luxury" to be able to lobby a Biden administration on progressive issues, insisting that the focus right now should be on winning the White House.

Mark Meadows: "We are not going to control the pandemic"

White House Chief of Staff Mark Meadows defended Vice President Pence's decision to continue traveling and campaigning despite his exposure to aides who have tested positive for COVID-19, saying Sunday that Pence is exempt from CDC guidelines because he is "essential personnel."

Why it matters: CDC guidelines call for people who have been exposed to the virus to quarantine for 14 days. Meadows said on CNN's "State of the Union" that Pence will wear a mask when he travels and argued that "he's not just campaigning," pointing to the Israel-Sudan normalization agreement announced by the White House last week.
