Naked Cowboy plays 'The Trump Song' at Trump Tower

The street performer known as the Naked Cowboy on Monday performed a song in honor of President-elect Donald Trump, in the lobby of the Trump Tower in New York, before flashing onlookers with the word "Trump" printed on the back of his underwear.

The Naked Cowboy, whose real name is Robert John Burck, has become known for performing in New York's Times Square wearing only cowboy boots, a cowboy hat and white briefs.

On Monday, he strolled into the lobby of the Trump Tower wearing his trademark cowboy hat and boots, but also a robe printed in the pattern of the American flag. He then sang a song praising some of the policies President-elect Donald Trump promised to enact if elected, such as building a wall between the U.S. and Mexico.

When he finished, he turned around and lifted up his robe to show the crowd the word "Trump" printed on the back of his underwear. He then repeated the song before walking out.

The performance came as Trump has been conducting days of meetings with prospective members of his new administration.
