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.

The big picture: Trump has made clear to Meadows that an important part of his job is to “find the leakers” — a wickedly difficult task that has plagued all three of Meadows’ predecessors.
