Mark Cuban dubbed Donald Trump's $5 million challenge to Barack Obama was "one of the DUMBEST things ever," and has raised trump to his own $1 million challenge. Cuban went live on Fox4 in Dallas on Thursday night to make his offer known to the public.

"Donald, you shave your head, $1 million to any charity you want," Cuban said.

Cuban said he was willing to up the offer to $2 million, if it would help motivate Donald to seal the deal, but it all seems very unlikely that he would agree.
