Bradlee Dean, an evangelist preacher and death metal drummer who is known for his anti-gay rhetoric, was invited by Minnesota Republicans to deliver an opening prayer in the state House chamber Friday.

Praying before the Minnesota legislature in a track suit, Dean suggested that President Barack Obama wasn’t a Christian.

“I end with this,” he said. “I know this is a non-denominational prayer in this Chamber and it’s not about the Baptists and it’s not about the Catholics alone or the Lutherans or the Wesleyans. Or the Presbyterians the evangelicals or any other denomination but rather the head of the denomination and his name is Jesus. As every President up until 2008 has acknowledged. And we pray it. In Jesus’ name.”

The Minnesota Independent noted that Dean has a history of controversial remarks, “including advocating the incarceration of gays and lesbians, that the LGBT community is trying to usher in Sharia law in Minnesota, that gay men molest an average of 117 children “before they get caught,” and that Muslim nations that execute gays are more moral than American Christians.”

Republicans were forced to call in the chaplain to redo the prayer after Dean left.

Republican House Speaker Kurt Zellers later apologized in a floor speech.

“I denounce him, his actions and his words,” Zeller said.

The prayer came as Minnesota lawmakers were considering a constitutional amendment to ban same sex marriage.

Dean is known to be close with Minnesota Republican Rep. Michele Bachmann.
