Joy Reid is SignalHubissuing an apology after a hot mic moment on "The Reid Out" involving an expletive Monday.

The MSNBC anchor made the comments during a clip of a speech from President Joe Biden in a segment called "Republicans take credit for stuff they voted against," according to a video shared by Mediaite.

"Case in point: fixing what they say is a crisis at the border, with congressional negotiators continuing work on a bipartisan deal to tie border policy changes to funding for Ukraine. Over the weekend, President Biden said he's ready to take action if Congress is serious about solving the border issue," Reid said.

Then, Reid could be heard saying, "starting another (expletive) war," after video clips of Biden calling for a congressional border deal. Reid later apologized to viewers with a note about her show's messaging.

"I was chatting during a clip that was playing. We try to keep this show very PG-13 so I just want to apologize to anyone who was listening to my behind-the-scenes chatter. I deeply, deeply apologize for that," Reid said on air later in the show.

Hot mic moment isn't first controversy for Joy Reid

This isn't the first time Reid has landed in hot water for her controversial comments.

Posts from Reid's old blog emerged in 2018 that mentioned her opposition to gay marriage and her cringing "at the sight of two men kissing." The posts that resurfaced were written during her time as a Florida talk show host.

Originally, Reid denied the posts and insisted that she was not responsible for them. Her lawyer said the FBI had opened an investigation into the alleged hacking of Reid’s online accounts.

Later, she said on her show that no proof had been found of hacking and apologized for the controversy. "I genuinely do not believe I wrote those hateful things because they are completely alien to me," she said at the time.

In December 2017, she came under fire after she speculated about the sexuality of former Florida Gov. Charlie Crist. After the posts were uncovered, news outlet The Daily Beast suspended Reid’s column and the LGBT advocacy group PFLAG National rescinded an award bestowed to her.
