Rep. Morgan Carroll, D-Aurora, announced this week that she'll seek the Senate seat being vacated by term-limited Sen. Bob Hagedorn, D-Aurora, next January.
Carroll, who is the House Majority Caucus chair, was not expected to seek to move over to the Senate until former Rep. Michael Garcia, D-Aurora, suddenly resigned earlier in the week after being accused by a lobbyist of making unwelcome sexual advances.
Su Ryden, an Aurora businesswoman, is expected to seek the Democratic nomination for Carroll's house seat.
