Sen. Brown Not Sure Of Next Step After Defeat

Republican Sen. Scott Brown says he doesn't know what's in his future after his defeat Tuesday to Democratic challenger Elizabeth Warren.

In a letter to supporters Wednesday, Brown said he couldn't have asked for better allies and friends during the campaign.

Brown makes no mention of speculation about his political future- including the possibility he could run for governor in two years or try to reclaim a Senate seat if President Obama taps Sen. John Kerry to serve as Secretary of State.

In his letter, Brown said he's not sure what's comes next, "except a lot of time back at home with the family come January" when Warren steps into the Senate office.

Brown said he was proud to offer Massachusetts what he called "three years of independent representation in the Senate."
