Chicago Mayor Lori Lightfoot says she is sorry she insulted a police union leader aloud on Wednesday.

It's no secret that Mayor Lightfoot does not get along with the Fraternal Order of Police (FOP).

However, it was still surprising when, during the City Council meeting, she was caught on a microphone insulting the group's second in command.

As Patrick Murray got up to speak, Lightfoot could be heard saying, “oh, back again, this FOP clown."

The mayor later apologized and said she should not have made the remarks out loud.

Murray was at the council meeting to support the officers who were fired by the police board last week for their involvement in the Laquan McDonald shooting.
