Evan McMullin is only on the ballot in 11 states, but his Presidential campaign is sparking anger from supporters of Donald Trump.

Last week, a white nationalist Trump supporter unleashed a robocall attack against McMullin, claiming he is a “closet homosexual.” The man behind the calls, William Johnson, also outed McMullin’s mother.

“Evan has two mommies. His mother is a lesbian, married to another woman,” Johnson says in the call.

The robocall went out to more than 200,000 residents in Utah, a state where McMullin is performing well in polls. Analyst Nate Silver places McMullin’s chances of winning Utah between 18 to 25 percent.

“I’ve stood for liberty and equality in this race; it’s natural for @realDonaldTrump’s white supremacists to attack me. A fight worth having,” McMullin tweeted on Monday.

A retired Central Intelligence Agency officer, McMullin is running for President as an Independent. He is part of the fallout from a Republican Party wrecked by Trump’s insurgency and yet the robocalls from Johnson may have done more good than harm in making the electorate more aware of third party options.

“Another desperate attack from GOP nominee @realDonaldTrump and his racist supporters as he continues to lose ground in Utah,” McMullin tweeted.

McMullin, 40, denies he is gay, but the robocall was correct about his mother. McMullin told the Salt Lake Tribune he believes in traditional marriage, but still loves his mother.

“My mother has a different view. That is OK. I love her very much. And she is one of my best friends. She is a wonderful mother,” McMullin told the newspaper.

As for Johnson, the man behind the robocalls, he has quite a dubious background. According to the Southern Poverty Law Center, Johnson believes in deportation of non-whites as a “pre-emptive strike in defense of real Americans.”
