Singer Clay Aiken called on MSNBC to fire Joy Reid Thursday amid new revelations that the AM Joy host published a photoshopped image of Sen. John McCain (R-AZ) as the Virginia Tech gunman on her former blog.

“Ok. I’m truly over it with this mess. First the homophobic posts, then the 9/11 ‘Truther’ posts, and now this nonsense with manipulating images,” Aiken fumed. “And watch @JoyAnnReid blame this on a hacker… or better yet… Ambien. It’s time for her to go too.”

In replies to his followers, Aiken said that Reid has “lost all credibility.”

She's no longer effective when she had lost ALL credibility. Sorry. It hurts to say it, because I was a loyal viewer and agree with her so often. But her credibility is totally shot. — Clay Aiken (@clayaiken) May 31, 2018

BuzzFeed uncovered the post depicting McCain as a mass murderer:

The October 2007 post, titled “Baghdad John Strikes Again,” discusses then-GOP Presidential nominee John McCain’s infamous claim that he would “follow Osama bin Laden to the gates of hell.” The image appears at the end of the post, which was apparently penned by Reid. The McCain post is the latest in a series of archived items from Reid’s blog that have embarrassed the AM Joy host and her network. Though Reid apologized for several homophobic posts last December, she later attributed others to a hacker. Reid subsequently admitted that she could not substantiate this claim after news reports knocked down the evidence her private cybersecurity expert provided. Reid and MSNBC have both pointed to an ongoing FBI investigation into the alleged breach.

This development comes one day after Buzzfeed reported the embattled MSNBC host published 9/11 conspiracy theories on her now-defunct blog.

In March 2006, Reid published a blog post which promoted a video titled Loose Change 9/11, an 80-minute film produced by Infowars founder Alex Jones, that alleges the U.S. government was behind the Islamic terror attack on the twin towers of the World Trade Center.

In December, the MSNBC host apologized for publishing homophobic remarks about former Flordia Gov. Charlie Crist, in which she called the Republican-turned-Democrat “Miss Charlie.”

In another post, Joy wrote “Stop pretending, brother,” later adding, “It’s okay that you don’t go for the ladies.”

1/x From 2007 to 2009 @joyannreid authored a dozen homophobic posts not only attempting to out Charlie Crist as gay, she attacked & mocked him for being so. She repeatedly referred to him as "Miss Charlie" and tagged posts about him under "gay politicians." (thread) pic.twitter.com/tRYvJ3lTc8 — Abolish ICE (@Jamie_Maz) November 30, 2017

2/x Joy constantly refers to Crist mockingly as "Miss Charlie" and insinuates that his marriage is a fraud to cover up his being gay. pic.twitter.com/2E7i8rCq8C — Abolish ICE (@Jamie_Maz) November 30, 2017

3/x She makes a joke about John McCain "tapping" Crist, says Crist spent his honeymoon ogling male waiters and thinking about how he didn't want to see his wife naked, and mocked Crist's big gay wedding. pic.twitter.com/KmWxJymc3J — Abolish ICE (@Jamie_Maz) November 30, 2017

“This note is my apology to all who are disappointed by the content of blogs I wrote a decade ago, for which my choice of words and tone have legitimately been criticized. As a writer, I pride myself on a facility with language—an economy of words or at least some wisdom in the selection,” Reid said in a statement published by The Wrap.

“However, that clearly has not always been the case,” she added.

In late April, a progressive Twitter user found more anti-gay posts from the Reid Report, but Reid claimed that they were maliciously added by a hacker; her lawyer said the FBI was investigating the claim. Investigations from both right and left-wing news outlets decisively disproved the “hacking” claims. Reid went on air and apologized for them, though she continued to claim “I genuinely do not believe I wrote those hateful things.”

MSNBC has kept Reid on its staff and has not further addressed the controversy.
