BILLINGS, Mont. — Vice President Mike Pence has canceled plans to attend a Trump campaign fundraiser in Montana following revelations that the event’s hosts had expressed support for the QAnon conspiracy theory.

President Trump’s reelection campaign said on Saturday that Pence’s schedule had been changed, but the campaign did not provide a reason or say whether the fundraiser might be held at a later time. The change comes after it was reported Wednesday that hosts Cayrn and Michael Borland in Bozeman, Montana, had shared QAnon memes and retweeted posts from QAnon accounts.

The baseless conspiracy theory alleges Trump is battling an entrenched bureaucracy and sex trafficking ring run by pedophiles.

Three Republicans seeking election in Montana also had been scheduled to attend the fundraiser: U.S. Sen. Steve Daines, who faces a November challenge from Democratic Gov. Steve Bullock; U.S. Rep. Greg Gianforte, a Republican running for governor; and state auditor Matt Rosendale, a candidate for the U.S. House.

Pence, Daines and the other Republican candidates are still scheduled to hold a campaign rally Monday afternoon in Belgrade, just east of Bozeman.

Daines campaign spokesperson Julia Doyle said the first-term senator does not know the Borlands nor “does he know what QAnon even is.” She referred questions on whether the event would be rescheduled to the Trump campaign.

The Borlands have donated over $220,000 to Trump’s reelection bid, the bulk of which was made in Caryn Borland’s name, and they were guests at the national GOP convention last month.

The QAnon narrative has grown to include other long-standing conspiracy theories, gaining traction among some extreme Trump supporters. The movement is often likened to a right-wing cult. Some followers have run for office, primarily in the Republican Party, though some have been independent or run as third-party candidates. Trump has refused to say QAnon is false.

Pence has said it’s a conspiracy theory and last month told CBS, “I don’t know anything about QAnon, and I dismiss it out of hand.””

The Borlands have shared multiple QAnon social media posts, as well as other discredited conspiracies.

Michael Borland prominently featured several QAnon “Q” logos on his Facebook page. Caryn Borland has retweeted or engaged with QAnon Twitter accounts. In April, she responded to a pro-Trump Tweet from a QAnon account by replying “Always” with a praying hands emoji.

The Borlands did not immediately return telephone messages Saturday seeking comment.
