A former Republican New Hampshire House Speaker is seeking the U.S. Senate seat held by Democratic incumbent Jeanne Shaheen.
Bill O'Brien is planning to announce his candidacy Tuesday afternoon at the American Legion hall in Manchester.
O'Brien would be the second Republican seeking the position. Retired Brig. General Don Bolduc announced his campaign last month. He served in the Army for 36 years.
Shaheen's seat is seen as a possible Republican pickup in 2020 following her competitive 2014 re-election race and fellow Democratic Sen. Maggie Hassan's tight win over an incumbent Republican in 2016.
Republican hopes at winning Shaheen's seat took a blow back in May when the state's leading Republican, Gov. Chris Sununu, opted to run for re-election to the governor's office instead of challenging Shaheen.
