Trump just went berserk over a phone call – here’s what set him off

President Donald Trump responded to a couple of throwaway lines by MSNBC's Hallie Jackson with a furious denial that accidentally confirmed the comment he was initially pushing back against.

The president again spent the morning Wednesday tweeting in apparent response to reports he was watching on TV, as he's done all week, and seemed to have been angered by remarks Jackson made in passing during a discussion of a Washington Post report.

"The president called up the friend of our show Bob Costa overnight on an unrelated topic," Jackson said, "and Bob smartly asked him about all of these subpoenas that House Democrats are issuing against the Trump administration, and the president made the argument to the Post, 'Hey, I cooperated plenty with Robert Mueller, what do I have to cooperate with Congress for?"

Jackson had introduced the segment by pointing out that the president had called Costa, the Post reporter, and Trump responded about five minutes later with an angry denial that also confirmed the broadcaster's account about who had initiated the call.
