Democrat Jeanne Shaheen has defeated Republican Scott Brown in the New Hampshire Senate race, ABC and NBC reported. Brown conceded late Tuesday night.

Shaheen, who has represented New Hampshire in the Senate since 2009, accused Brown of lacking ties to the state throughout her campaign. Brown, who served as a Massachusetts Senator from 2010 to 2013, moved to the Granite State in 2013, saying it was for "strictly personal" reasons.

Brown officially announced his run for Senate in April 2014. He had several slip-ups throughout his campaign, once contrasting himself with the Massachusetts delegation and more recently struggling with New Hampshire geography.
