(CNN) Former Trump campaign manager Corey Lewandowski will not run for Senate in New Hampshire after considering a potential campaign earlier this year, he announced Tuesday.

"After much consideration I have decided to forgo a campaign for the US Senate," he tweeted . "While taking on a career politician from the Washington swamp is a tall order, I am certain I would have won. My priorities remain my family and ensuring that @realDonaldTrump is re-elected POTUS."

He had been huddling with New Hampshire political operatives and confidants this summer -- joined in some meetings by his wife -- as he mulled a potential Senate bid in the Granite State, multiple sources familiar with the discussions told CNN at the time. He also appeared to have his former boss's blessing, a voice that could help sway Republican primary voters, just before Lewandowski appeared at a campaign rally in New Hampshire with Trump earlier this year.

"I think he would be fantastic," the President said of his former campaign manager in a radio interview ahead of the rally. "I don't think he's made that decision yet. I will say this -- if he ran, he would be a great senator. If he ran and won, he'd be a great senator. He would be great for New Hampshire. He would be great for the country."
