CHARLOTTE, N.C. -- In the video, President Obama is seen talking to someone on the phone, saying that he's counting on him to take his job of hosting the convention's primetime coverage this Thursday seriously.
When Obama hangs up, you see who he was talking to. Harold and Kumar, both stoned.
Kumar is played by Kal Penn, who used to work for the Obama White House.
In addition to hosting Thursday night, he'll talk to the convention Tuesday.
Amber Riley of "Glee" will sing the national anthem and Ledesi will perform.
