President Donald Trump thanked a Fox News host who praised him, and social media users mocked him for seeking the broadcaster's approval.

Greg Gutfeld, who hosts a self-titled program that airs late Friday and Saturday and also appears on Fox News programs such as "The Five," praised Trump as a "game changer" and "once in a century kind of leader" in an appearance flagged Thursday night by the president's social media director Dan Scavino.

Trump thanked Gutfeld on his own Twitter account Friday morning, and sought the broadcaster's continued approval.

"Wow! Thank you Greg," Trump tweeted. "Hope I live up to your expectations."

The mockery was swift.
