Adelita Grijalva awaits swearing-in 14 days after election to U.S. House— here's how that compares to other special election winners - Ballotpedia News

At the time, Johnson said he could not swear in Grijalva during a pro forma session: "The House is not on the floor doing business this week, but we will do it immediately early next week as soon as everyone returns to town. We have to have everybody here and we'll swear her in."

Not including the special election in Arizona's 7th Congressional District, there have been three other special elections this year to fill vacancies in the 119th Congress (2025-2027). Johnson swore in the three winners—Randy Fine (R-Fla.), Jimmy Patronis (R-Fla.), and James Walkinshaw (D-Va.)—of those special elections the day after their respective elections. Both Fine and Patronis were sworn in during a pro forma session.

During the 113th through the 118th Congresses, three other special election winners—Reps. Tom Tiffany (R-Wisc.), Mike Garcia (R-Calif.), and Kweisi Mfume (D-Md.)—were sworn in during pro forma sessions. All three of those special elections were to fill vacancies in the 116th Congress (2019-2021).
