Harry Reid returns to Congress after exercise injury

Several weeks after suffering a severe injury while exercising, Senate Minority Leader Harry Reid, D-Nevada, heads back to work on Tuesday, his staff tells CBS News.

The Senate will convene Tuesday morning for the day's business, including several votes on amendments to a bill approving the construction of the Keystone XL oil pipeline.

At 8:30 p.m., lawmakers will be called to order in the chamber of the House of Representatives in preparation for President Obama's State of the Union address. Though he'll be back in D.C., Reid will not attend the president's speech.

Reid tweeted a picture of himself on Tuesday in his office on Capitol Hill:

Reid, 75, was working out with an exercise band at his home in Nevada last December when the exercise band broke. The top Senate Democrat fell, breaking four ribs and several bones near his right eye, his office said in a statement at the time.

In a recent radio interview with KNPR, Reid suggested there's a possibility the vision in his right eye will not be fully restored.

"This isn't anything that's a slam dunk," he said. "I had a serious injury in my eye, there's blood accumulation there and they're hoping it resolves itself. As long as there's blood in my eye, it's hard to see."

Reid, who was first elected to the Senate in 1986 and has led the Democratic caucus since 2005, will be up for reelection in 2016. Republicans have pushed Nevada's popular GOP governor, Brian Sandoval, to challenge Reid.

There's some speculation Reid might decide to forego what promises to be a tough reelection bid, but when the senator was asked by KNPR whether his injury might factor into that decision, he suggested it would not.

"No, not really. No, no," he said.
