Arizona Attorney General Kris Mayes and Rep.-elect Adelita Grijalva are suing the House of Representatives over Speaker Mike Johnson’s failure to seat the new member.

“.@AZAGMayes and I are going to court to ensure that 800,000+ Arizonans in AZ-07 are no longer silenced,” Grijalva wrote in a statement on X, formerly Twitter. “@SpeakerJohnson’s obstruction has gone far beyond petty partisan politics — it’s an unlawful breach of our Constitution and the democratic process.”

In a complaint filed in federal court in Washington, D.C., Mayes and Grijalva argue the House is depriving Arizona of representation in Congress and impeding Grijalva from exercising her authority as a lawmaker.

They call on a judge to allow another qualified person to swear in Grijalva if Johnson continues to stall.

Grijalva was elected to represent Arizona’s 7th Congressional District on Sept. 23, but has yet to be sworn in by Johnson.
