CONCORD, N.H. (AP) — Former Florida Gov. Jeb Bush has made a foray into New Hampshire politics, supporting Republican Scott Brown in his campaign for the U.S. Senate.

Bush is a possible contender for the GOP's 2016 nomination for president and dipping a toe into New Hampshire, with its first-in-the-nation primary, is considered a requirement for any presidential hopeful.

On his Twitter feed Monday, Bush posted a photo with Brown, Brown's wife and daughter, and another man taken in Massachusetts, where he was attending a fundraiser.

In the post, the son and brother of former presidents said it was "great" to be with Brown and he was "proud to support his campaign for U.S. Senate."

Brown faces a primary to take on first-term incumbent Democrat Jeanne Shaheen.
