Rep. Maxine Waters will not be traveling to Alabama and Texas this weekend for two scheduled appearances, citing an increase in threatening messages sent to her congressional offices this week, including at least one death threat.

“As the President has continued to lie and falsely claim that I encouraged people to assault his supporters, while also offering a veiled threat that I should ‘be careful,’ even more individuals are leaving [threatening] messages and sending hostile mail to my office,” the California Democrat said in a statement, CNN reported.

“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 cancelled this weekend,” Waters 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 received criticism from Republicans and Democrats alike earlier this week after she told supporters at a rally last Sunday to continue protesting Trump administration officials in public and refusing to let them be served at local businesses.

White House press secretary Sarah Huckabee Sanders was ousted from a Lexington, Virginia, restaurant last week. Department of Homeland Security Secretary Kirstjen Nielsen was recently shouted out of a Mexican restaurant in D.C. and faced protesters outside her home in Virginia.
