Why is the US House speaker refusing to seat an elected Democrat? | Moira Donegan

Adelita Grijalva won a landslide election for her Arizona seat. But Mike Johnson is defying the will of the voters

The people of Arizona's seventh congressional district - a vast territory extending across the state's south, along the Mexican border - have been denied representation in Congress for weeks. That's because Mike Johnson, the Republican House speaker, has refused to swear in Adelita Grijalva, their representative-elect, who won a special election to fill the seat vacated by her father, the late Raul Grijalva, in a landslide late last month. Grijalva, a Democrat, has been largely ignored by the speaker. Unlike sworn representatives, she has to go around the Capitol with an escort. There's an office with her name on the door, but she hasn't been allowed inside, and has worked instead out of a conference room on another floor.

It is an unprecedented abuse of procedural power on the part of the speaker, one that has had the effect of silencing a political opponent and denying representation to the citizens of her district. In refusing to seat Grijalva, Johnson has defied the will of Arizona's voters, and effectively nullified, at least for the time being, a legitimate congressional election. He has persisted in this even in defiance of his own promises, after saying on Friday he would seat her this week once the House returned to session - and then telling lawmakers they wouldn't reconvene this week after all. Last week, Grijalva showed up to a three-and-a-half-minute pro forma session, hoping to be sworn in then. (Johnson has sworn in other representatives at pro forma sessions in the past.) But the Republican presiding over the session, Morgan Griffith, ignored the effort. On a weekend talkshow, Grijalva said she had heard absolutely nothing" from the speaker about the timing of her swearing in.
