Recent reports about Rep. Marjorie Taylor Greene confirm what Republicans already knew: She is an unserious person whose only claim to fame is lunacy and conspiracy-theorizing.

This was obvious when Greene first announced her candidacy in Georgia. She had voiced her support for the deranged QAnon conspiracy theory, questioned whether Muslims should be allowed to hold public office, suggested the federal government was responsible for the 9/11 terrorist attacks, and claimed the Parkland school shooting was a false-flag operation. Republicans welcomed her into the caucus anyway, rewarding her with two committee assignments.
