Rep. Maxine Waters has canceled two scheduled appearances after she said on Thursday, June 28, she received threatening messages and one death threat, CNN reported.

The recently canceled events come amid criticism the California Democrat received after she publicly condemned President Donald Trump and the administration's "zero-tolerance" immigration policy earlier this week. Waters encouraged her supporters to "show up" and confront Trump administration officials in response to the mass family separations at the U.S-Mexico border. Her comments came after Trump administration officials had been protested in public spaces; White House press secretary Sarah Sanders was recently asked to leave a restaurant in Virginia.

Homeland Security Secretary Kirstjen Nielsen was heckled out of a Mexican restaurant on June 19 just hours after she defended the administration separating immigrant children from their families at the border. 

"Let's make sure we show up wherever we have to show up," Waters told a crowd, according to CNN. "And 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. We've got to get the children connected to their parents."

Waters' speech centered on the importance of continuing to protest the Trump administration and its immigration policies. Trump responded to Waters' comments by calling her an "extraordinarily low IQ person." The president also accused Waters of inciting harm to his supporters which the congresswoman has vehemently denied. 

Congresswoman Maxine Waters, an extraordinarily low IQ person, has become, together with Nancy Pelosi, the Face of the Democrat Party. She has just called for harm to supporters, of which there are many, of the Make America Great Again movement. Be careful what you wish for Max!

"I believe in peaceful, very peaceful protests," Waters said on Capitol Hill, according to NBC News. "I have not called for the harm of anybody. This president has lied again when he's saying that I've called for harm."

According to a statement released to CNN, Waters said she has received a "very serious death threat."

"There was one very serious death threat made against me on Monday from an individual in Texas which is why my planned speaking engagements in Texas and Alabama were [canceled] this weekend,"  she said. "This is just one in several very serious threats the United States Capitol Police are investigating in which individuals threatened to shoot, lynch or cause me serious bodily harm."

Waters also noted that while she supports citizens' rights to protests, she handles death threats differently. 

"I don't cry about protests," Waters said, according to CNN. "People protest me all the time. People come to my district office. That's their right. The only time I have anything to say about protests is when they threaten to kill me; then I turn that in. Otherwise, protests is the American way."
