Chris Cillizza reports that Senator Tim Johnson (D-SD), who underwent emergency brain surgery in December of last year, following an intracerebral bleed caused by a congenital arteriovenous malformation, returned to the Senate for the first time today. He also made a speech earlier in the week in South Dakota saying he will indeed seek a third term: "I believe I have been given a second chance at life. I will take that second chance and work harder than ever to be the best I can be for each and every South Dakotan." Superb.

In less happy news, Rep. Paul Gillmor (R-OH) died last night of an apparent heart attack at age 68. Our condolences to his family and friends. His seat will be filled with a special election.
