Prominent white nationalist William Johnson, an ardent supporter of Donald Trump’s campaign, has ceased a scheduled Wednesday evening robocall set to go out in Utah, in which he claimed that independent threat Evan McMullin is gay. "Please be informed that I have disabled the anti-Evan McMullin robocalls that went out Monday and Tuesday and is scheduled to finish today," Johnson wrote in a letter to reporters. "I will not send the rest of the robocalls out to Utah or anywhere else. I have stopped the campaign immediately."

"I am sorry for the mean-spirited message and I humbly retract its contents. I sent the robocalls out because Utah is a strong family-values state and America and the West is gripped by an extreme and fatal malady: failure to marry and have children. The white birth rate is so astonishingly low that Western Civilization will soon cease to exist. I felt that Evan McMullin typified that perfidious mentality."

"Donald Trump’s campaign has repudiated my robocall and many people from Utah and beyond have excoriated me for it as well. Just as Donald Trump has issued a heart-felt apology for his past locker room talk, I too issue a heartfelt apology for this robocall. I should not have sent out. I am truly sorry."

Johnson, who has contributed $1,500 to Trump's campaign, told The Daily Beast that neither campaign has reached out to him about the call.
