Mark Cuban mocks Donald Trump on Late Show with Stephen Colbert

Mark Cuban and Stephen Colbert have plenty of sick burns for Donald Trump.

Mark Cuban stopped by The Late Show with Stephen Colbert on Wednesday night to lend a hand with the comedian’s coverage of the 2016 Republican National Convention.

The Mavericks owner has been a pretty outspoken critic of the party’s presidential candidate, Donald Trump, and he “took the gloves off” to give the politician a piece of his mind.

In the clip, the Shark Tank star pokes fun at Trump for his companies’ multiple bankruptcies, his reportedly tiny hands and his failed Trump University program.

Cuban has previously raised questions about the financial solvency of the Trump campaign, and has said that the real estate magnate frequently overstates his true wealth in interviews.
