With five written words Thursday morning, one of Missouri’s most controversial state lawmakers spawned a U.S. Secret Service investigation, potentially endangered her own political career — and flung St. Louis squarely into the middle of America’s raging racial-political debate in the wake of the unrest in Charlottesville, Va.

“I hope Trump is assassinated!” Democrat, D-University City, wrote during a morning Facebook exchange, referring to Republican President Donald Trump.

She quickly deleted her post, but not quickly enough. By midafternoon, the political verdicts of her own party were rolling in:

U.S. Sen. Claire McCaskill, D-Mo.: “I condemn it. It’s outrageous. And she should resign.”

U.S. Rep. William Lacy Clay, D-St. Louis: “(C)alling for the assassination of the President is a federal crime. … (She is) an embarrassment to our state. She should resign immediately.”

Missouri Democratic Party Chair Stephen Webber: “The … Party will absolutely not tolerate calls for the assassination of the President. I believe she should resign.”

Missouri Senate Democratic Caucus leader Sen. Gina Walsh: “(She) should be ashamed of herself for adding her voice to this toxic environment.”

Republican Gov. Eric Greitens said in a statement: “We can have differences in our country, but no one should encourage political violence. The senator should resign.”

Lt. Gov. Mike Parson, a Republican, and state Auditor Nicole Galloway, a Democrat, also called for Chappelle-Nadal’s resignation.

In an interview, Chappelle-Nadal acknowledged she wrote the offending line on her personal Facebook page in response to another commenter before deleting it.

“I didn’t mean what I put up. Absolutely not. I was very frustrated. Things have got to change,” Chappelle-Nadal told the Post-Dispatch. “It was in response to the concerns that I am hearing from residents of St. Louis. I have deleted it, and it should have been deleted, but there is something way more important that we should be talking about.”

She added later: “I am not resigning … What I said was wrong, but I am not going to stop talking about what led to that, which is the frustration and anger that many people across America are feeling right now.”

Chappelle-Nadal said her comment stemmed from frustration over the events in Charlottesville over the weekend, in which a white supremacist protester allegedly rammed his car into a group of counterprotesters, killing a 32-year-old woman.
