FILE - In this file photo taken Wednesday Nov. 3, 2010, in Wheeling, Ill., Illinois Sen.-elect Mark Kirk, R-Ill., speaks to media as he celebrates his election win. Nearly a year after a stroke left him barely able to move the left side of his body, U.S. Sen. Mark Kirk is expected to climb the 45 steps to the Senate’s front door this week _ a walk that’s significant not just for Illinois’ junior senator, but also for medical researchers and hundreds of thousands of stroke patients.
