Sununu served a single term in the Senate after his election to the seat in 2003. Before that, he served in the House of Representatives for six years. He is the older brother of the state’s long-time former governor Chris Sununu, and the son of New Hampshire governor and George H.W. Bush chief of staff John H. Sununu.
“New Hampshire’s Senate seat is one to watch this cycle," RNC Spokesperson Kristen Cianci told Townhall. "The President’s endorsement underscores what a priority this race is and that Republicans are fully prepared to show up in November.”
The candidate, who has received endorsements from a bevy of Republican senators, has announced big fundraising numbers ahead of his primary election

Trump has also indicated that an endorsement may be coming in the highly-contentious Texas Senate primary between Attorney General Ken Paxton, Senator John Cornyn, and Rep. Wesley Hunt.
🚨NEW: I asked President Trump if he has changed his mind on endorsing in Texas’ Republican Senate primary and he tells me he’s “giving it a serious look.”

“You’ll be seeing soon,” he says.
A win for Sununu would mean Republicans would gain an extra seat to solidify their majority in the Senate after the midterms.
