Maxine Waters claims, with absolutely zero evidence, that President Donald Trump sending federal agents to help with the protests in Portland is a trial run of what he might do if he loses the upcoming election. This is simply one of the more stupid things she has suggested. She said, specifically, "As a matter of fact, it has been suggested that this is a trial run by the president of the United States who may be organizing to not accept what happens when we have the election if he’s not elected."
If Trump loses, he will go home and sit on Twitter for the next few years and call it fake, but he's not going to throw a massive temper tantrum and send federal agents to cities. This is absurd extremist talk from Maxine Waters. It's not even realistic.
