BOSTON (AP) — U.S. Sen. Scott Brown attended the final day of the Republican National Convention on Thursday, saying it's important to show that moderate Republicans have a place in the party.

Brown also said it was a special day for Massachusetts since the state's former governor Mitt Romney is accepting the GOP nomination for president.

"We have somebody who's going to be nominated to run for the presidency of the United States and I think that's a good thing for our state, so I'm honored to be here and be part of it," Brown told reporters at the Tampa, Fla., gathering of Republicans.

Brown, who did not address the convention, said he respects Romney even though they don't agree on every issue. Brown has credited the former governor with helping him win the 2010 special election to fill the seat formerly held by longtime Democratic Sen. Edward Kennedy, who died in 2009.

As he runs for his first full six-year term, Brown has regularly portrayed himself as a "Scott Brown Republican" who is willing to work with either party.

"Me being here is important in that it shows that someone who's a pro-choice moderate Republican is here, is part of the big tent that we have and should have and will continue to have with my involvement here," he said.

"While I don't agree with everything in the platform and or with Gov. Romney, I have a lot of respect for him and vice versa," he added. "I'm going to continue to do my very best to let my position be known on a whole host of issues."

Brown's Democratic challenger Elizabeth Warren said Brown can't have it both ways.

"He can't say 'I'm not part of that' and then say that 'I strongly support Mitt Romney to be president of the United States and Paul Ryan to be vice president of the Unites States,'" Warren told reporters during a campaign stop in Boston.

"He can't vote with the Republican Party every time it matters and then try to distance himself from it," she added.

Warren also said she is putting the finishing touches on her speech to the Democratic National Convention.

She is scheduled to address the Charlotte, N.C., gathering Sept. 5 just before former President Bill Clinton delivers his speech. Gov. Deval Patrick, one of several co-chairs of President Obama's re-election committee, also is slated to speak to the convention.

Warren said her speech will echo some of the same themes as her campaign.

"Mostly I'll talk about the things I've been talking about for a very long time and that is how middle class families are drawing the short end of the stick over and over and Washington is rigged to work for the big guys," she said.

The race is already the most expensive in Massachusetts history with Election Day still more than two months away. The candidates already have raised more than $52.9 million combined.
