Waters’ calls for physical resistance against the Trump administration “doesn’t obviously reflect credibly on the House,” Judicial Watch director Tom Fitton told ‘Fox & Friends’ on Thursday.“Look, she’s telling people: ‘get a crowd together, confront Trump cabinet members...tell them they’re not welcome, push back’. That’s the very definition of mob violence.”

Fitton’s group sent a letter to the House Office of Congressional Ethics, demanding an investigation into whether Waters’ remarks, delivered to a crowd of supporters in Los Angeles almost two weeks ago, violated rules that demand that all members of Congress behave in a way that reflects well on the institution.

After White House Press Secretary Sarah Huckabee Sanders was booted out of a Virginia restaurant for her politics, Waters called for more harassment of Trump officials.

“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 that they are not welcome, anymore, anywhere,” she told the cheering crowd in Los Angeles.

Waters was savaged by President Donald Trump, who responded by calling the congresswoman “unhinged,” and “an extraordinarily Low IQ person.” She was also criticized by establishment voices in both parties and by progressive icon Senator Bernie Sanders (I-Vermont), who said that, in his view, “people have the right to go into a restaurant and have dinner” undisturbed.

Waters denied that she intended to incite violence, and she vowed to keep fighting back like a “wounded animal.”

Her words apparently struck a chord with some of the anti-Trump #Resistance, who have been spurred into action against the president by his administration’s ‘zero tolerance’ immigration policies, particularly after news broke of 2,400 children of illegal immigrants separated from their border-jumping parents and held in detention centers.

On Monday, Environmental Protection Agency chief Scott Pruitt was accosted in a restaurant and given a dressing down over his environmental record by a Washington, DC teacher and activist. Pruitt resigned on Thursday.
