At least three prominent Texas GOP officials took part in a Dallas conference this weekend with ties to the QAnon conspiracy theory movement, where a former Trump administration official advocated for a military coup on the U.S. government.

Texas GOP Chairman Allen West, Republican U.S. Rep. Louie Gohmert and Agriculture Commissioner Sid Miller each delivered remarks at the “For God & Country Patriot Roundup,” which featured Michael Flynn, Donald Trump’s first national security adviser. Flynn pleaded guilty to lying to the FBI in 2017 but later recanted and received a presidential pardon from Trump.
