Illinois Democrat Sen. Roland Burris will not run in 2010

WASHINGTON (CNN) — Sen. Roland Burris, D-Illinois, is expected to announce Friday that he will not run for a full six year term next year, a well-placed Democratic source tells CNN.

Burris is currently serving the remaining two years of President Obama’s Senate term, but he has never been embraced by Democratic leaders in Illinois or Capitol Hill.

A Burris spokeswoman would not comment on the senator’s future political plans, but his office did release an advisory Thursday stating that he would make a “major announcement” during a speech Friday afternoon in Chicago. A spokesman for Senate Majority Whip Richard Durbin, D-Illinois, said that Burris had spoken to Durbin but would only say “we will let him speak for himself” on Friday.
