Vice President Mike Pence and top officials from President Donald Trump’s campaign are slated to attend a Montana fundraiser next week hosted by a couple who have expressed support for the QAnon conspiracy theory, according to an event invitation obtained by The Associated Press and a review of social media postings.

The hosts of the fundraiser, Caryn and Michael Borland, have shared QAnon memes and retweeted posts from QAnon accounts, their social media activity shows. The baseless conspiracy theory posits that Trump is fighting entrenched enemies in the government and also involves satanism and child sex trafficking.

Beyond Pence, the Sept. 14 fundraiser in Bozeman, Montana, is expected to draw influential figures in the president’s orbit including Kimberly Guilfoyle, a top Trump fundraising official who is dating Donald Trump Jr., GOP chairwoman Ronna McDaniel, Republican National Committee finance chairman Todd Ricketts and RNC co-chairman Tommy Hicks Jr., the event invitation shows.
