Republicans committed to derailing Donald Trump's candidacy for president are reportedly poised to announce their conservative alternative, a virtual unknown named Evan McMullin who is a 40-year-old former CIA officer and current policy director for the House Republican conference, according to BuzzFeed News. Is Evan McMullin married? He would be the only presidential candidate who is not married.

McMullin told ABC News in a statement:

In a year where Americans have lost faith in the candidates of both major parties, it’s time for a generation of new leadership to step up. It’s never too late to do the right thing, and America deserves much better than either Donald Trump or Hillary Clinton can offer us. I humbly offer myself as a leader who can give millions of disaffected Americans a conservative choice for President.

According to ABC News, McMullin was a Mormon missionary who attended Brigham Young for undergraduate school, then earned a master's in business from The Wharton School at the University of Pennsylvania, the shared alma mater of his rival Donald Trump.

Unlike Trump, McMullin has a long record of service as a United Nations High Commissioner for Refugees and as a CIA officer. He left the CIA in 2011, went to work for Goldman Sachs, and in 2013 joined the House Republican Conference.

McMullin's presidential bid is back by several "Never Trump" Republicans including Mitt Romney mega donor John Kingston, consultant Rock Wilson, and GOP operative and pollster Joel Serby, ABC News adds.

Until word of his candidacy started to come out, McMullin was best known for his TED Talk titled "Why saying 'never again' to genocide is not enough."

Leading up to the announcement, BuzzFeed reported that McMullin has given Trump plenty of harsh criticism calling him "authoritarian" in one tweet.

He also joined the chorus of Americans calling to see Trump's tax returns.

McMullin also came out forcefully in support for the Gold Star Kahn family against Trump, writing on his Facebook page, according to the Independent Journal:

As someone who served our nation in war, I find Donald Trump’s religious attacks on Ghazala Khan, the mother of a fallen U.S. soldier, profoundly despicable. Her son gave everything for our country and she, like thousands of other American mothers, has also made a painful lifelong sacrifice. No one who fails to understand this is fit to be our commander-in-chief.

BuzzFeed also reported that McMullin is planning to file his paperwork to officially launch his candidacy on Monday. But while he might have enthusiasm from sectors of the GOP totally committed to defeating Trump, he will face serious challenges trying to get on the ballot across all 50 states and raising money.
