U.S. Rep. Joe Wilson of South Carolina has gone to the hospital because of an extended fever.
Wilson's office said in a short statement Wednesday that the Republican was admitted.
He is best known for being rebuked by the House for shouting, "You lie!" at President Barack Obama in 2009. Wilson later apologized.
The statement contained no other details, including when the congressman was admitted, if he remained in the hospital, or the name of the hospital.
Wilson's office said last week that he was taking antibiotics to treat symptoms of Lyme disease.
Previously a little-known lawmaker, after the remark, he drew campaign donations from across the country, and he now regularly appears on cable TV news shows and is a sought-after guest at Republican fundraisers.
