President Trump said he would walk away from a planned meeting with North Korea's leader, Kim Jong Un, if it looked like the two sides were not going to be able to reach a deal.
"If we don't think it's going to be successful ... we won't have it," Trump said at a joint press conference with Japanese Prime Minister Shinzo Abe Wednesday at Trump's Mar-a-Lago resort. "If the meeting when I'm there is not fruitful, I will respectfully leave the meeting."
