U.S. Sen. Scott Brown is defending his decision to attend the final day of the Republican National Convention, saying it's important to show that moderate Republicans have a place in the party.
Brown also said Thursday is a special day for Massachusetts since the state's former governor, Mitt Romney, is accepting the GOP nomination for president.
Brown says he respects Romney even though he doesn't agree with him on every issue. Brown says he'll continue to be an independent voice.
Brown's Democratic challenger, Elizabeth Warren, says Brown can't have it both ways.
Warren says Brown can't say he supports Mitt Romney for president and vote with Republicans "every time it matters" — and then try to distance himself from the party.
The race is already the costliest in state history.
