Mr. Pappas, a 44-year-old Democratic congressman, is the first major candidate to enter the race to succeed the retiring Senator Jeanne Shaheen.

Rep. Chris Pappas (D-NH) announced his run for retiring Sen. Jeanne Shaheen‘s (D-NH) seat to represent the Granite State in the Senate, leaving the door open for fierce competition for his House seat.

On Sunday, President Donald Trump supported a possible Senate bid for former Republican New Hampshire Gov. Chris Sununu. "I support him fully," Trump said. "I hope he runs. He's been very nice to me over the last year or so. I hope he runs. I think he'll win the seat."
