“You are about to see something on the Fox News that has never happened, that we believe, in the history of White House reporting," co-host Steve Doocy announced live on air. "And that is the president of the United States is just outside the press room and it looks like he is en route to our location.”

Trump tweeted that he might do so at 7:50 a.m., while live-tweeting segments from the show.

“Wow, the highest rated (by far) morning show, @foxandfriends, is on the Front Lawn of the White House. Maybe I’ll have to take an unannounced trip down to see them?” he tweeted.

Trump is a known fan and regular viewer of the morning Fox show and often tweets quotes from its hosts and guests.

Fox News announced Trump would appear on the show in a press release at 8:19 a.m.

Reporters thronged Trump as he left the White House to cross the lawn. A White House press pool report noted that Trump's public appearance happened three hours before the pool "call" time, which is when the White House estimates the president's schedule calls for media coverage.

In the interview, Trump discussed the Department of Justice's internal watchdog report released on Thursday, the Republicans' immigration compromise bill and his summit with North Korean leader Kim Jong Un, among other topics.
