Vice President Mike Pence on Friday posted a tweet that shows him posing with a Florida police officer who was wearing a badge associated with the QAnon conspiracy theory movement.

The photo showed Pence greeting SWAT-team members from the Broward County Sheriff’s office at an airport there on Friday.

“Grateful for the courageous members of law enforcement who helped with my visit to Florida this afternoon,” Pence captioned the since-deleted tweet.

The officer in the photo standing directly to Pence’s right was wearing a patch emblazoned with the letter “Q,” an apparent reference to “QAnon,” a collection of far-right conspiracy theories that gained traction online.

After the image gained traction online, the vice president’s account deleted the tweet.

A spokesperson for the Broward County Sheriff’s Office told the Miami New Times in a statement: “The patch is not authorized by BSO. This matter will be addressed immediately.”

Followers of QAnon spread conspiracy theories, including that a deep-state plot is working to undermine President Trump.

The anonymous person who started the thread goes by the pseudonym “Q,” while his followers consider himself the “anons.”
