(CNN) – He may have served as U.S. Senator from Massachusetts, but Scott Brown is dropping more hints that he might make a bid to return to Capitol Hill from neighboring New Hampshire.
Brown, who owns a vacation home in the Granite State, will serve as the keynote speaker at the New Hampshire GOP's holiday reception on Dec. 19. The news, first reported Tuesday by WMUR in Manchester, New Hampshire, was confirmed by CNN.

Brown's already made a bunch of trips to New Hampshire this year to speak to local Republican groups.
Also Tuesday, Brown is out with a new opinion piece that fuels more speculation that he's eyeing a Senate bid in New Hampshire. In the op-ed on FoxNews.com, Brown highlights what he describes as the negative effects of the federal health care law in New Hampshire, rather than in Massachusetts.
"For example, in New Hampshire, only 16 of the state's 26 hospitals are available on the federal exchange, meaning patients must either pay more to keep their current doctor or seek inferior care elsewhere," Brown writes. "Neither is a good option."
While not naming Democratic incumbent Sen. Jeanne Shaheen, who's up for re-election next year, Brown appears to take a shot at her (and other Democrats who support the Affordable Care Act, better known as Obamacare), by writing that "Not only is President Obama to blame here, so too are every single one of the Democratic senators who forced this fiasco on the American people."
In January 2010 Brown, then a little known Massachusetts GOP state senator, pulled an upset, winning a special election to serve the final three years of the term of the late Democratic Sen. Ted Kennedy, who had died the previous summer. Last year, Brown lost his re-election bid to Democratic challenger Elizabeth Warren.
Since leaving Capitol Hill, Brown has taken an on-air contributor gig at Fox News, has served as a colonel in the Army National Guard's office at the Pentagon and as an attorney at the Boston law firm of Nixon Peabody.
Scott passed on running in a special election in Massachusetts earlier this year to fill the term of former Democratic Sen. John Kerry, who stepped down to become U.S. Secretary of State. And he announced earlier this year that he wouldn't make a 2014 bid for an open governor's seat in the Bay State.
Last month, in another hint about a possible run for the Senate in New Hampshire, Brown dropped the 'MA' from his Twitter handle.
When asked by reporters earlier this year if he would consider running for office in the Granite State, Brown said, "I don't think I'm done with politics, but I'm not going to rule out anything right now because I really haven't thought a heck of a lot about it."
Brown also made a recent trip to Iowa, the state that kicks off the presidential caucus and primary calendar, stoking some speculation that he might have designs on the White House in 2016.
Former Sen. Bob Smith announced over the weekend that he plans to move back to New Hampshire from Florida, to run for the Senate seat he lost in a Republican primary in 2002. Two candidates, conservative activist Karen Testerman and former state Sen. Jim Reubens, are already in the race, but several stronger candidates, including former Sen. John Sununu, passed on a Senate run.
