A state senator from Omaha has announced that he's running for Congress, hoping to unseat Republican incumbent Lee Terry.

Sen. Brad Ashford announced his intention late Wednesday and said he will file for the 2nd Congressional District race on Thursday. The 64-year-old Ashford is the second Democrat to enter the race. Omaha City Councilman Pete Festersen dropped out in December after two months on the campaign trail. 

Omaha Republican businessman Dan Frei is challenging Terry in the primary. Terry has held the seat since 1999.

Ashford is chairman of the Legislature's Judiciary Committee. He switched his party affiliation to Democrat in August.
