“I’ve been hitting them hard, and I think I might’ve had something to do with it,” said Trump at a campaign stop on Saturday, hours after four American prisoners long held in Iran were freed.

On the campaign trail, Trump has often criticized the Obama administration for failing to secure the release of those prisoners in its negotiations with the country.

“It’s part of my staple thing,” said Trump. “You know, I go crazy when I hear about this. You go absolutely wild, because how is it possible? We have one who’s in there who’s a reporter for the Washington Post. He didn’t do anything wrong by the way.”
