Former Vice President Joe Biden and Sen. Bernie Sanders were alone on Sunday night's debate stage for the first time.

The big picture: The candidates faced off without a studio audience to avoid unnecessary exposure to the coronavirus, with debate moderators Univision anchor Ilia Calderon, CNN chief Washington correspondent Jake Tapper, and CNN political correspondent Dana Bash the only others in the Washington studio.

Scoop: How the White House is trying to trap leakers

President Trump's chief of staff, Mark Meadows, has told several White House staffers he's fed specific nuggets of information to suspected leakers to see if they pass them on to reporters — a trap that would confirm his suspicions. "Meadows told me he was doing that," said one former White House official. "I don't know if it ever worked."

Why it matters: This hunt for leakers has put some White House staffers on edge, with multiple officials telling Axios that Meadows has been unusually vocal about his tactics. So far, he's caught only one person, for a minor leak.
