WASHINGTON --Senate Majority Leader Harry Reid was taken to the hospital early Friday morning after not feeling well, and remained for observation, his spokesman said.

Reid, the Nevada Democrat who turned 74 this month, led the chamber Thursday night through its second midnight session in recent days amid steep partisanship. He is not expected to be at work Friday, as the Senate wraps up its final workday of the year.

Reid decided to go to the hospital "as a precaution," said the senator's spokesman Adam Jentleson. "Tests have been conducted and everything is normal. Doctors have asked that he remain in the hospital for observation so he will not be working today.”

In 2005, Reid, a slight man and former amateur boxer, suffered a mini-stroke, but has otherwise maintained a vibrant schedule and appeared in good health. He rises early and usually takes a morning walk or does yoga before heading to the Capitol for what are often long days.

More recently, the senator was briefly hospitalized following a 2012 car accident in Las Vegas.

The Senate has been in knots this week, as lawmakers try to finish the year's business under continued partisan discord.
