In the wake of the horrific church shooting in Sutherland Springs, Texas, on Sunday, actor Wil Wheaton decided to slam House speaker Paul Ryan’s note of condolence on Twitter.

“Reports out of Texas are devastating. The people of Sutherland Springs need our prayers right now,” Ryan wrote. The former “Star Trek: The Next Generation” and “Stand By Me” star responded, tweeting, if “prayers did anything, they’d still be alive.”

“The murdered victims were in a church. If prayers did anything, they’d still be alive, you worthless sack of sh–,” wrote Wheaton.

A couple of hours of Twitter users slamming Wheaton’s flippant response caused the actor to walk back those comments and apologize several times, saying things like, “I’m not talking about religion or faith at all. I am talking about the speaker of the house who does nothing to address gun violence.”

As the barbs flew at him, with people tweeting angry responses such as, “One thing to attack a politician, it’s another to attack the innocent dead and all religion. Looks like you’re the worthless sack of sh–,” Wheaton addressed them in a series of tweets: “Hey, real and actual people of faith: I hear you. I apologise for insulting you, in my rage at Paul Ryan’s refusal to address gun violence.” He added, “Your faith is your business and people like Paul Ryan exploit it while they hide behind words without deeds, and people continue to die.”

Wheaton was certainly not the only celebrity taking to Twitter to call out Republicans for upholding the Second Amendment. Chelsea Handler outright blamed Republicans for the shooting in Texas.
