Oct. 22 (UPI) -- New Hampshire's ex-U.S. Sen. John Sununu is making a bid for his former Senate seat after his past rival for the job announced her retirement more than 15 years after he left Washington.

Sununu, part of a decades-long New Hampshire GOP political dynasty, revealed Wednesday in a campaign video that he will toss his name in the 2026 Senate race to fill the seat being vacated by retiring Democratic Sen. Jeanne Shaheen.

He will face U.S. President Donald Trump's former New Zealand and Samoa ambassador, ex-Sen. Scott Brown, R-Mass., in the state's Republican Party primary.

"Maybe you're surprised to hear that I'm running for the Senate again. I'm a bit surprised myself," the past lawmaker said.
