After Maxine Waters called for violence and harassment of Trump officials and supporters, the violence and intimidation tactics have ratcheted up on the left. And now a Florida man has been arrested after threatening to kill U.S. Rep. Brian Mast’s children out of anger revolving around the recent immigration debate.

Key allegedly called Mast’s office and told the person who answered the phone, “I’m going to find the Congressman’s kids and kill them. If you’re going to separate kids at the border, I’m going to kill his kids. Don’t try to find me because you won’t.”

Key is a regular volunteer for the Democratic Party of Martin County and Planned Parenthood, according to WPTV.

CBS 12 reports that Key called Mast’s office at least 478 times.

Key apparently told an FBI investigator in an interview that he did not threaten to kill Mast’s children but wanted him separated from them.

Recently, Maxine Waters called for violence against Trump officials and supporters. The American Mirror has the details:

“Already, you have members of your Cabinet that are being booed out of restaurants,” Waters said in LA on Saturday, as the crowd erupted, “who have protesters taking up at their house, who say, ‘No peace, no sleep. No peace, no sleep,’” she continued.

“And guess what,” she predicted, “we’re going to win this battle because while you try and quote the Bible, Jeff Sessions and others, you really don’t know the Bible.

“God is on OUR side!” she declared, as the crowd went wild. “On the side of the children. On the side of what’s right. On the side of what’s honorable.”

“And so, let’s stay the course. Let’s make sure we show up wherever we have to show up 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,” she yelled.

Waters remarks were then marred by a screeching microphone.

“Mr. President, we will see you every day, every hour of the day, everywhere that we are to let you know you cannot get away with this!” she yelled.
