Mark Kirk Recovery: Video Showcases Senator's Rehab Work After Stroke (VIDEO)

Five months after suffering a serious stroke, U.S. Senator Mark Kirk (R-Ill.) says he's well on his way to recovery.

The senator's office released a video this week detailing Kirk's efforts at the Rehabilitation Institute of Chicago, where he's working to regain his ability to walk and speak normally.

"I suffered a stroke on the 21st of January, and thanks to the doctors nurses and profs at the Rehabilitation Institute of Chicago, the RIC, I'm walking again," Kirk says in the video, which features footage of the Senator performing a variety of rehabilitation exercises. "Getting to my hope to climb the 45 steps that my staff counted from the parking lot to the Senate front door to fight for the people of Illinois."

Kirk returned to his Highland Park home last week after being treated for three months at the RIC as an inpatient.

Dr. Richard Harvey, the RIC's medical director who's been working with the Senator, says he's optimistic that Kirk will make a full mental recovery and will recover most of the mobility in his left side of his body.

Ever a politician, Kirk thanks his supporters in the video before sneaking in references to his agenda once he returns to the Senate.

"I want to thank everyone, especially for the patience they have given me to recover from a big stroke," Kirk says in the video. "I want to thank the people of Illinois for granting me the honor to represent them in the united states senate. i cant wait to go back to work to vote to spend less and borrow less and tax less to help fix our economy."
