Lauren Boebert Has Blood Clot Removed After Hospitalization for Leg Swelling

Representative Lauren Boebert, a far-right ally of former President Donald J. Trump from Colorado who is part of the razor-thin Republican majority in the House, had surgery on Tuesday to remove an acute blood clot in her leg, her campaign said.

Ms. Boebert, 37, who is running for re-election this year, was admitted to UCHealth Medical Center of the Rockies in Loveland, Colo., on Monday after experiencing severe swelling in her upper left leg, according to her campaign. It said that she was expected to make a full recovery.

The campaign disclosed that doctors diagnosed Ms. Boebert with May-Thurner syndrome, which the Cleveland Clinic describes as a condition in which a major artery in the leg compresses a major vein, disrupting blood flow.

A stent was inserted during the surgery, the campaign said.

Ms. Boebert, who is part of a group of right-wing provocateurs in the House that includes Representatives Matt Gaetz of Florida and Marjorie Taylor Greene of Georgia, announced in December that she would run in a more conservative district than the one she now represents.

During the midterm elections in 2022, she narrowly staved off a challenge from Adam Frisch, a Democratic businessman and former Aspen city councilman, who is running again in her current district.

A series of departures from the House Republican caucus later this month will mean G.O.P. lawmakers can afford just a single defection from party-line votes when all members are present.
