The officer, Charlie Rispoli, a 14-year veteran of the Police Department in Gretna, referred to Ocasio-Cortez, D-N.Y., in a post Thursday as “this vile idiot.”

The post continued, saying she “needs a round — and I don’t mean the kind she used to serve,” a reference to her past work as a bartender, according to a screenshot of his comment obtained by nola.com, which covers New Orleans.

He was responding to a post by the satirical website tatersgonnatate.com with the headline “Ocasio-Cortez on the Budget: ‘We Pay Soldiers Too Much.’”

Wayne Rau, a city councilman and the mayor pro tem of Gretna, a city of about 18,000 people across the Mississippi River from New Orleans, condemned Rispoli’s post in an interview Sunday.

“I’m pretty appalled by it,” Rau said. “I don’t think this is a representation of the Police Department of the city of Gretna.”

Asked whether Rispoli’s Facebook post was a threat, he said, “I’m not sure how to take that post.” He said it should be up to the city’s police chief, Arthur Lawson, to decide on any disciplinary or criminal action.

In addition to Rau, there are four other members on the Gretna City Council. Three were not immediately available for comment Sunday. The fourth, Jackie Berthelot, directed questions to the Police Department.

Efforts Sunday to reach Rispoli, who appeared to have deactivated his Facebook account, were unsuccessful. Corbin Trent, a spokesman for Ocasio-Cortez, declined to comment. Lawson, who is an elected official, did not immediately respond to a request for comment Sunday.

The chief told nola.com that he was disturbed by the post.

“I will tell you this: This will not go unchecked,” he said. “I’m not going to take this lightly and this will be dealt with on our end. It’s not something we want someone that’s affiliated with our department to make these types of statements. That’s not going to happen.”

The chief told the website on Friday that the post appeared to violate the department’s social media policy but he did not think it rose to the level of being a threat.

Ocasio-Cortez is part of a quartet of first-year Democrats in the House who have received death threats and were told by President Donald Trump to “go back where you came from” in a racially charged post on Twitter.

Belinda Constant, the mayor of Gretna, said Sunday that she had been out of the state and was not immediately prepared to comment. “I will be looking into the situation,” Constant, a Democrat, said.

Eva Malecki, a spokeswoman for the U.S. Capitol Police, declined to say whether the agency was investigating.

“The mission of the United States Capitol Police is to protect and serve Congress,” she said. “However, we do not discuss how we carry out our protective responsibilities.”
