Welker grilled Trump on his repeated campaign pledge not to start any new wars — a line of inquiry which was not well received by the president. The post ‘Did You Break That Promise?’ NBC’s Kristen Welker Grills Trump On ‘No New Wars’ Pledge — President Snaps in Response,

An NBC News reporter’s comments about California’s elections and the 2020 presidential race caused President Trump to storm out of their interview Sunday. Kristen Welker sparred with the commander-in-chief over his claims the state’s voting was rigged as the counting continues and Democrat candidates suddenly enjoy a late stream of votes from mail-in ballots.

Trump is the quintessential bully who tried every physical and rhetorical tactic bullies employ to avoid responding to her pointed but highly relevant questions. When Welker refused to back down in the face of Trump’s insults, he acted like the spoiled child he is and walked out of the interview.

President Trump accused California officials of "cheating on the election" during an interview with NBC’s Kristen Welker, pointing to the state’s slow vote count as evidence that the result was being manipulated.
