Sen. Harry Reid, the outgoing majority leader, broke ribs and bones in his face after a piece of exercise equipment broke and caused him to take a tumble.
His office says Reid, a Democrat from Nevada, was treated at University Medical Center in Las Vegas.
"Senator Reid will return to Washington this weekend and be in the office Tuesday as the Senate prepares to reconvene. His doctors expect a full recovery.
"Senator Reid was first brought to St. Rose Dominican Hospital in Henderson by his security detail. He was then transferred to UMC for further testing, where he was admitted overnight as a precaution."
