State Sen. Maria Chappelle-Nadal, D-University City, should resign. If she doesn’t, her fellow senators probably will vote for her ouster.

Last week in a Facebook posting, the senator said President Donald Trump should be assassinated. Quickly realizing the error of her ways, she deleted it. However, the damage to her constituents, the Missouri Senate, the state and to herself was in place. There were immediate calls for her to resign. Members of her own party, including U.S. Sen. Claire McCaskill, joined the resign chorus.

“I condemn it. It’s outrageous. And she should resign,” Sen. McCaskill said.

Gov. Eric Greitens, a Republican, was among the state officials who said she should resign. No one in the Senate came to her defense. Missouri Democratic Party Chair Stephen Webber called her remarks “indefensible.” He added that the Missouri Democratic Party “will absolutely not tolerate calls for the assassination of the president.”

When the nation’s highest leaders in government are calling for unity and an end to racial violence, for a state senator to make such a statement is inexcusable. Chappelle-Nadal, who is black, said she posted the statement in a moment of anger over President Trump’s remarks about the protests and violence in Charlottesville. That is supposed to be justification for calling for the assassination of the president?

Her remarks disqualify her for any elective office. She will be termed out at the end of the 2018 session, but she needs to go now. The FBI and Secret Service are investigating, which they do whenever a threat like that is made against the president.

Chappelle-Nadal is defiant in saying she won’t resign. She admits her posting was a mistake. Her remarks sound like she is a victim!

Lt. Gov. Mike Parson, presiding officer of the Senate, said he will ask senators to remove her from office if she does not resign. The Missouri Constitution provides that a member of the Senate can be expelled upon a two-thirds vote of the elected members of the Chamber. That type of action hasn’t occurred in decades.

Chappelle-Nadal is an embarrassment to her constituents and to the state of Missouri. She is not fit to serve in a public office.
