From Roll Call:

Rep. Lane Evans (D-Ill.) will announce this afternoon that he is retiring from Congress, sources said Tuesday.
The 12-term Congressman has battled Parkinson’s disease for more than a decade and his health has been ailing for at least the past month. He has not cast a vote since Feb. 14.
Because the Illinois primary has already taken place, Democratic leaders in the southwestern 17th district will decide who succeds Evans on the ballot. The district only slightly favors Democrats. Republicans nominated Andrea Zinga in last week’s primary.
