WASHINGTON (AP) — Democrats are ramping up the pressure on House Speaker Mike Johnson to swear in Rep.-elect Adelita Grijalva, an Arizona Democrat who won a special election last month to succeed her late father.

The delay has attracted mounting attention this week, with Johnson challenged by lawmakers, reporters and even C-SPAN viewers about why Grijalva hasn't been given the oath of office. Johnson has said repeatedly that she will be sworn in when the House returns to session. He blames the government shutdown for the delay.

Here's a look at where the situation stands:

She is the daughter of Rep. Raul Grijalva, a staunch progressive who died in March. He served more than two decades in the House, rising to chairman of the House Natural Resources Committee, where he helped shape the nation’s environmental policies.

Adelita Grijalva has been active in local politics, first serving at the school board level and subsequently on the Pima County Board of Supervisors, becoming just the second woman to serve as chair.

She easily won a special election Sept. 23 to serve out the remainder of her father's term. She will represent a mostly Hispanic district in which Democrats enjoy a nearly 2-1 voter registration advantage over Republicans.

Grijalva was gracious to her soon-to-be Democratic colleagues as they welcomed her to the U.S. Capitol last month, even as she and her future staff were officially considered visitors to the building.

“I think it’s great to be able to be in a room with those who will be my colleagues, but then you very quickly realize that you are not part of the club yet,” Grijalva said Thursday in an interview with The Associated Press. “If I had big money to bet, I would bet that if I were a Republican representative waiting in the wings, I would have already been sworn in by now.”

She said she's worried about the precedent that is being set by her delayed swearing-in.

“The bedrock of our democracy is free, fair, unobstructed elections,” she said. “And if Speaker Johnson believes this is, as I do, then he will quit toying with our democratic process and swear me in.”

Members of the House have been mostly back in their home districts since Sept. 19. That's when Republicans passed a continuing resolution to fund the government through Nov. 21. Johnson's decision to send lawmakers home was intended to pressure the Senate into passing that funding measure — a tactic that so far hasn't worked.

Johnson has yet to schedule any floor votes since then, though the House has occasionally met in pro forma sessions, which are generally short affairs lasting just a few minutes during which no votes are taken.

“We will swear her in when everybody gets back,” Johnson told reporters this week.

Lawmakers who win special elections generally take the oath of office on days in which legislative business is conducted, and they are welcomed with warm applause from members on both sides of the aisle. They give a short speech as family and friends watch from the galleries.

Yet there is precedent for doing it differently. On April 2, Johnson swore in Republican Reps. Jimmy Patronis and Randy Fine, both of Florida, less than 24 hours after they won their special elections, during a pro forma session.

Johnson says the circumstances were unique because the House had unexpectedly gone out of session that day. Patronis and Fine had already arranged for their families, friends and supporters to be in Washington.

“As a courtesy to them and their families, we went ahead and administered the oath to an empty chamber. It was no fun. They didn't get the same pomp and circumstance everybody else gets,” Johnson said Thursday on C-SPAN when asked by a caller about Grijalva. “We're going to administer the oath as soon as she gets back.”

Democrats have little leverage to force Johnson to seat Grijalva so long as the House is in recess. But they are keeping up the pressure.

In an unusual scene Wednesday, Arizona's two Democratic senators — Mark Kelly and Ruben Gallego — confronted Johnson outside his office about Grijalva's situation.

“You just keep coming up with excuses,” Gallego said to Johnson. The speaker called it a publicity stunt.

Democrats have also taken to the floor during pro forma sessions to try to have Grijalva sworn in. The presiding officer has ignored them every time.

“Representative-elect Adelita Grijalva should be sworn in now. It should have happened this week, should have happened last week. It needs to happen next week,” House Minority Leader Hakeem Jeffries told reporters Thursday.

Republican Rep. Thomas Massie of Kentucky, defying GOP leadership, has been gathering signatures on a petition to trigger a vote on legislation that would force the release of federal files on Jeffrey Epstein. And he's just one name away from succeeding.

Grijalva has said she'll sign the petition once she takes office, providing Massie the 218 signatures needed to trigger a vote.

Democrats say Johnson is stalling on Grijalva's swearing-in, as well as on bringing the House back to Washington, because he wants to push off any Epstein vote.

Johnson rejected that accusation during his appearance on C-SPAN. “This has zero to do with Epstein.”

Grijalva said she tries to not be a “conspiracy theorist” and initially disagreed with supporters and allies who warned her that she wouldn't be seated in Congress because of the Epstein bill.

“I thought, no way, he’s gonna swear me in. It’ll be fine,” she said. “Here we are two weeks later.”
