President Trump's first sit-down television interview after his historic summit with North Korean dictator Kim Jong-un is expected to be with his friend and confidant, Fox News host Sean Hannity, Axios has learned.

The details: Hannity is already in Singapore, and a source who spoke to him told Axios that Trump had promised him the interview.

Axios approached Hannity and White House Press Secretary Sarah Sanders for comment; neither responded. But on Monday a Fox News spokeswoman confirmed the interview.

Hannity's interview with Trump will air in full on Fox News' Hannity on Tuesday at 9 p.m. ET and will take place on location at the Capella Hotel on Sentosa Island in Singapore, according to the spokeswoman.

Behind the scenes: Hannity's close relationship with the president is well documented, and neither man makes any secret of it. Hannity backed Trump during the campaign, even appearing in one of his commercials, and they kibitz regularly on the phone late at night, according to sources familiar with their conversations. Trump loves watching Hannity tear into Robert Mueller and others he considers his political enemies.
