Was Trump calm or furious when he left the infrastructure meeting?

Twenty-four hours after Donald Trump waltzed out of the meeting with Democrat leaders to discuss his $2 trillion infrastructure plan there are now two totally different versions of events, one put out by Nancy Pelosi and her Democrat cohorts who were there at the time, and the other described by Sarah Sanders, White House press secretary. I wonder which version we should believe!! The Democrats say it was all pre-planned drama by the president, that he never intended to have the meeting because he hadn't worked out how he was going to pay for the infrastructure programme and that his walk-in and walk-out theatrics was just a ploy to blame them for.....everything. Sarah Sanders dismissed this as ridiculous on CNN and said the president hadn't preplanned anything but reacted as he did because of Pelosi's pre-meeting attack on Trump, accusing him of the crime of covering up nefarious activities. Sanders was one of those in the White House who had spotted Pelosi's denunciation and tipped off Trump just before he was due to sit down with her and her fellow Democrats to discuss infrastructure. I reckon hearing that would have made Trump spit blood, but according to Sarah Sanders, the president was perfectly calm. He just popped into the meeting room to inform the already assembled Democrats that it was no longer possible to do business with them if they were going to continue to spend all their time and energy on investigating him for alleged misdoings which were all rubbish, fake news and witchhunty stuff. Then he "calmly" walked out of the room, leaving Pelosi and co flabbergasted. I can't really imagine Trump was feeling calm at all. He doesn't really do calm. And anyway he went straight off to the Rose Garden to hold a press conference and waved his arms around while condemning Pelosi for having the temerity to accuse him of a cover-up of anything. He didn't look calm in the Rose Garden. He and Pelosi are deadly enemies. She stands up to him like no one else and he hates her for it. He is, after all, the President of the United States. How dare this woman antagonise him so much. Ah well, Trump should do a bit more reading of America's political history. This is what happens to sitting US presidents. They get accused of things all the time. But Trump is so thin-skinned he gets upset at every political attack against his status and dignity. He and Pelosi are never going to get along. However, instead of walking/storming out of the meeting Trump should have gone in and sat down and said the following: "Welcome Speaker Pelosi and delegates, I believe this is a very important meeting to discuss something which for once we can all agree on for the benefit of our nation. But I would like it on record that I am personally aggrieved by the statement made by Speaker Pelosi before we sat down here together. I found it insulting, bad manners, rude and unworthy of someone representing the Democratic Party. Now having said that, let's get down to business." What would Pelosi have done if he had said all that? Perhaps SHE would have walked out but then the press headlines might have been different and Trump would have scored some brownie points.
