A frail Dole returns to Senate to push for treaty

This handout video image provided by CSPAN2 shows former Senate Majority Leader Bob Dole, right, wheeled into the Senate Chamber on Capitol Hill in Washington, Tuesday, Dec. 4,2012, by his wife Elizabeth Dole. Frail and in a wheelchair, Dole was a startling presence on the Senate floor as lawmakers voted on a treaty on disabilities. The 89-year-old Republican was in the well of the Senate on the GOP side of the chamber, his wife Elizabeth nearby. Dole recently had been hospitalized but came to the Senate to push for the treaty.
