Her comments came a day after White House press secretary Sarah Huckabee Sanders was asked to leave a restaurant. Sanders' aborted dinner party followed spontaneous street protests against other Trump aides and allies, including Homeland Security Secretary Kirstjen Nielsen, who left a Mexican restaurant to cries of "Shame!" last week.
The flash mobs are inspired, in particular, by the Administration's new "zero tolerance" policy on undocumented migrants, whom Trump said should be stripped of their due-process rights.
But Waters's indignation encompasses the entire Trump presidency - not just what he's done, but who she says he is.
"He loves the strongmen and the dictators of the world because he wants to be just like them. He wants to run the country like them," the congresswoman told MSNBC yesterday, a day after her rally.
"And I want to tell you," she said, "for these members of his Cabinet who remain and try to defend him, they're not going to be able to go to a restaurant, to be able to stop at a gas station, to be able to shop at a department store. The people are going to turn on them, they're going to protest, they're going to absolutely harass them until they tell the president: 'No, I can't hang with you.' "
Her call to drive Trump officials from public life has made her a hero to many on the left - and has disturbed not only Trump supporters but some moderates and Democrats who accuse her of hastening the country's descent from centuries-old civic standards.
House Minority Leader Nancy Pelosi pushed back against Waters in a tweet that referenced a news story about her colleague's comments.
"In the crucial months ahead, we must strive to make America beautiful again," wrote Pelosi, who herself has been shouted down by left-wing protesters in San Francisco. "Trump's daily lack of civility has provoked responses that are predictable but unacceptable. As we go forward, we must conduct elections in a way that achieves unity from sea to shining sea."
Some Republicans were less subtle in their condemnation of Waters.
White House social media director Dan Scavino repeated an earlier Trump attack on Waters, tweeting: "The President is right. #LowIQMaxine."
Appearing on Fox News, House Majority Leader Kevin McCarthy said what Waters was doing is "very dangerous."
"She should apologise to the American public," McCarthy said. He also urged Pelosi to stand up to her.
"We're kind of back to the Colonial era in terms of public shaming, with virtual and symbolic stocks in the public square rather than literal ones," US historian Jon Meacham said.
He called this a perhaps uniquely "tribal moment" in the country's history.
Without mentioning Waters, David Axelrod, former President Barack Obama's onetime chief strategist, wrote that he was "kind of amazed and appalled by the number of folks on the Left who applauded" Sanders' expulsion from a restaurant.
As of Monday morning, the right-leaning Drudge Report was devoting the top section of its front page to a teeth-gritting photo of Waters, who "orders MORE public harassment of Trump aides."
And Waters's opponent in the upcoming election, Republican Omar Navarro, has tried to turn the outrage into a boost for his long-shot campaign to unseat her.
The congresswoman's office could not immediately be reached for comment on the reaction.
