On Wednesday night, I received a phone call from Anthony Scaramucci, the new White House communications director. He wasn't happy. Earlier in the night, I'd tweeted, citing a "senior White House official," that Scaramucci was having dinner at the White House with President Trump, the First Lady, Sean Hannity, and the former Fox News executive Bill Shine. It was an interesting group, and raised some questions. Was Trump getting strategic advice from Hannity? Was he considering hiring Shine? But Scaramucci had his own question—for me.

"Who leaked that to you?" he asked. I said I couldn't give him that information. He responded by threatening to fire the entire White House communications staff. "What I'm going to do is, I will eliminate everyone in the comms team and we'll start over," he said. I laughed, not sure if he really believed that such a threat would convince a journalist to reveal a source. He continued to press me and complain about the staff he's inherited in his new job. "I ask these guys not to leak anything and they can't help themselves," he said. "You're an American citizen, this is a major catastrophe for the American country. So I'm asking you as an American patriot to give me a sense of who leaked it."
