After promising a deal within 24 hours of taking office, then kicking off weeks of negotiations, Trump said Friday that he was about ready to give up. He hasn't set a deadline or said whether he would take any further action beyond walking away.

If either side continues to block a deal, "we're just going to say, 'You're foolish, you're fools, you're horrible people,' and we're going to just take a pass," Trump said Friday.
