Republican ex-congressman suggests colleagues 'had serious cognitive issues'

The Republican congressmen Louis Gohmert and Paul Gosar adopted such extreme, conspiracy-tinged positions, even before the US Capitol attack, that a fellow member of the rightwing Freedom Caucus thought they “may have had serious cognitive issues”.

Denver Riggleman, once a US representative from Virginia, reports his impression of his former colleagues from Texas and Arizona in a new book.

The Breach: The Untold Story of the Investigation into January 6th is published in the US on Tuesday. The Guardian obtained an early copy.

Riggleman is a former US air force intelligence officer who lost his seat in Congress after he officiated a same-sex marriage. In his book, he describes fallout beyond his primary defeat, including someone tampering with the wheels of his truck, endangering the life of his daughter.
