WIlliam Johnson attempted sent a robocall to Utah voters to influence the Mormon population to vote for Donald Trump on Oct. 31, 2016 Reuters

William Johnson, a prominent white nationalist and ardent Donald Trump supporter, issued a seemingly half-hearted apology by email Wednesday after he sent a robocall to Utah voters in which he claimed independent presidential candidate Evan McCullin was “a closet homosexual.”

“I sent the robocalls out because Utah is a strong family-value state and America and the West is gripped by an extreme and terrible malady: failure to marry and have children. The white birth rate is so astonishingly low that Western Civilization will soon case to exist. I felt that Evan McMullin typified that perfidious mentality,” he wrote.

In the same statement, Johnson said the Trump campaign had denounced the robocall scheduled to reach 193,623 Utah landlines. In the recording sent to voters Monday evening, Johnson warned his fellow Utah Republicans that they were dangerously close to losing the state for the first time since 1964, The New York Times reported.

“Evan has two mommies. His mother is a lesbian, married to another woman,” Johnson said in the robocall. After saying that McMullin supports same-sex marriage and citing that he does not have a girlfriend, he added, “I believe Evan is a closet homosexual.”

McMullin's mother is married to a woman, but he identifies as straight. As for his apology? It's true, there were more non-white babies than white babies last year.

Johnson’s remarks were an attempt to discourage the state’s largely socially conservative Mormon population from voting for a candidate other than the Republican nominee. Mormons have reportedly turned their back on Trump because of his many sexual remarks about women, polls show. McCullen, a former CIA operative, could become the first third party candidate to win Utah's electoral votes in 48 years, Politico reported.
