A Central Intelligence Agency veteran and former chief policy director of the House Republican Conference announced his independent presidential bid on Monday.

Evan McMullin plans to run as an alternative to GOP nominee Donald Trump, he announced Monday afternoon.

A campaign site went live mid-morning Monday with the tagline, "It's never too late to do the right thing. And if we work together, there's nothing we can't achieve."

"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," McMullin said in a statement to ABC News. "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."

BuzzFeed News reported that veteran Republican strategist Rick Wilson is expected to be involved with McMullin's campaign.

McMullin served in the national clandestine service at the CIA for 11 years, according to his LinkedIn profile.

He then went to work at Goldman Sachs in San Francisco before working for two years as a senior adviser at the House Foreign Affairs Committee. McMullin then served as chief policy director at the House Republican Conference for less than two years before resigning.

McMullin is "no longer an employee of the House Republican Conference," House GOP spokesperson Nate Hodson said, adding, "The House Republican Conference has zero knowledge of his intentions."

McMullin has been a vocal critic of Trump on social media. An alum of Brigham Young University, McMullin doesn't appear regularly on television and has spent most of career as a CIA officer. In 2011, he recieved his MBA from the Wharton School, the business school at the University of Pennsylvania.

He did a Tedx Talk in May on the subject of genocide.

There is still time for McMullin to get on the ballots of 24 states.

Though his candidacy faces many hurdles, sources say he will get the backing of serious GOP donors and fundraisers.

McMullin would be the latest in a series of relatively obscure third party hopefuls to be floated as a candidate. In April, retired Marine Gen. Jim Mattis declined to run after a "Draft Mattis" movement got underway. In June, attorney and writer David French announced he would not run after conservative leaders floated his name.
