Senate Minority Leader Harry Reid (D-Nev.) said Friday that he could permanently lose sight in his right eye as a result of his exercising accident on New Year's Day.
"They're very hopeful, but you know, this isn't anything that's a slam dunk," Reid said in an interview with NPR radio.
"I had serious injury in my eye, there's blood accumulation there, and we're hoping that resolves itself," he said. "As long as the blood is in the eye, it's hard to see."
"They're hopeful, and I'm just following their orders," he said.
Reid said that three days a week, he works out by doing sit ups, pushups and hundreds of strength-training exercises using large exercise bands. One of those bands snapped on New Year's Day, which forced him to fall and break bones around his eye, as well as three ribs.
But Reid brushed off the idea that the incident shows he's too physically weak to lead the Senate.
"I don't know how many people out there could sit down and do 250 pushups, or do the strength exercises I did with those bands," he said. "Hundreds and hundreds of times, hundreds of times, every week, three times a week."
"So, no one has questioned my physical ability," he said. "I've always been fairly confident in my ability to fight back, and I'm going to continue to fight back."
Reid also said the accident hasn't changed his mind about running for re-election in 2016.
Reid also said he supports President Barack Obama's threat to veto the Republican bill to approve the Keystone pipeline. "Good, I hope he does," Reid said.
