The Florida legislator sent a letter to the House Committee on Ethics requesting they open an investigation and shared the missive on Twitter.

Gaetz wrote that “Speaker Pelosi’s gesture was deeply offensive and appears to violate clauses 1 and 2 of House Rule XXIII,” which dictate the House’s official code of conduct.

“Her behaviour does not ‘reflect creditably on the House,’ nor does it follow “the spirit and the letter of the Rules of the House.”

Gaetz, in his letter, said Pelosi’s “unseemly behaviour certainly warrants censure.”
