Former U.S. Senator Bob Kerrey is reversing course and says he'll seek the Democratic nomination for the Nebraska seat he once held.
Kerrey's announcement comes just weeks after he publicly rejected a run to replace retiring Democratic Senator Ben Nelson. It's also just one day before Nebraska's candidate filing
The 1992 presidential candidate and former Nebraska governor previously said not running was in his family's best interest.
Kerrey's announcement is sure to create state party friction.
Fellow Democrat Chuck Hassebrook stepped into the race after Kerrey bowed out and gave up a University of Nebraska regent seat he's held for nearly 18 years.
Hassebrook was also granted a 10 month leave of absence from his position as director of the Center for Rural Affairs to run for the Senate.
