A new video of Ill. U.S. Sen. Mark Kirk has been released. It’s first since the Republican suffered a stroke in January.

The three minute video shows the Republican senator sitting up in an arm chair explaining his recovery process and thanking supporters.

“I want to thank everyone especially for the patience they have given me to recover from a big stroke,” Kirk said in the video. “I want to thank the people of Illinois for (giving) me the honor to represent them in the United States Senate. I can’t wait to go back to work.”

Kirk is seen going through different stages of his rehabilitation program. In one scene the senator is wearing a harness and is hooked up to a machine as he walks on a treadmill. In another he walks with a cane as a physical therapist assists him.

In the video, the senator has visible limited mobility to the left side of his body, but appears mentally sharp as doctors had previously reported.

Kirk suffered a stroke in January. He was released from the rehabilitation center last week, and he’s continuing his recovery as an outpatient. There are no details yet on when Kirk will be back at work.
