Washington (CNN) - Following weeks of speculation, Dan Senor, a Defense Department official during President George W. Bush's administration, has decided not to run for Senate in New York.
Senor, the husband of CNN anchor Campbell Brown, had been mulling a challenge to Democratic Sen. Kirsten Gillibrand. She was appointed last year to fill the seat vacated by Hillary Clinton. Republicans have yet to recruit a serious opponent for Gillibrand.
"Over the past few weeks, I took a very serious look at running for the Senate seat in New York," Senor said in a statement. "I ultimately decided this wasn't the right time in my family and business life for me to run.
Senor said he will "continue to look for ways to advance the policy debate here in New York, especially on issues that I am most concerned about: America's declining economic competitiveness, skyrocketing deficits and taxes, a national security strategy that is drifting and a morally equivalent foreign policy that is troubling."
He promised to stay involved in New York politics and lend a hand to whichever Republican decides to seek the seat.
Gillibrand also dodged a potential Democratic primary challenge earlier this month when former Tennessee Rep. Harold Ford decided against a bid.
