“This is absolutely insane — and extremely dangerous,” McCain tweeted in response to recent comments from Waters. “My father in law works in the administration, does this mean when we go out to dinner we should be ambushed?!?”

“Don’t ever again give me any of the ‘when they go low, we go high’ lip service,” McCain added, referring to former first lady Michelle ObamaMichelle LeVaughn Robinson ObamaMichelle Obama on 'Becoming': 'Sasha still hasn't read it' Michelle Obama seeks volunteers for local campaigns: There are 'no "off" years' Obama condemns 'hatred in all its forms' after New Zealand shooting MORE’s speech at the 2016 Democratic National Convention.

Waters on Saturday called for Trump staffers to be confronted in public spaces.

"If you see anybody from that Cabinet in a restaurant, in a department store, at a gasoline station, you get out and you create a crowd and you push back on them, and you tell them they’re not welcome anymore, anywhere,” Waters told supporters during a Los Angeles rally.

McCain's father-in-law, Douglas Domenech, is the current assistant United States secretary of the Interior for insular areas.

Waters’s rallying cry follows days of public outrage over the Trump administration’s practice of separating more than 2,000 migrant children from their parents after crossing the U.S.-Mexico border illegally.

Several Trump officials have been challenged in public as a result of the separations.

The owner of a Virginia restaurant asked press secretary Sarah Huckabee Sanders and her family to leave on Friday night.

Stephanie Wilkinson said she did so because of Sanders’s support of Trump’s desired ban of transgender people from the military.

Sanders works in an “inhumane and unethical” administration, Wilkinson said.
