Kirk has been hospitalized since Jan. 21, when he checked himself into Northwestern Lake Forest Hospital after suffering headaches and dizziness.

He was later transferred to Northwestern Memorial after doctors determined he was suffering an ischemic stroke and needed surgery to relieve swelling on his brain. Doctors removed a large section of his skull to relieve the swelling one week ago anda day after that procedure, Fessler that the senator was “doing better than expected” and even asked for his Blackberry within two days of first having the stroke.

A second surgery performed Wednesday involved removing two small pieces of tissue that had been rendered non-functional by the stroke.
