Former Massachusetts Sen. Scott Brown (R) invited the stars of anti-ObamaCare attack ads to a New Hampshire Republican dinner with him this month.

Brown’s move is the latest to spark renewed speculation over his potential run for Senate in the Granite State. He has made no secret of his interest in the race, appeared at local GOP events and publicly attacked Sen.

According to the Union Leader, Brown invited New Hampshire GOP activists Donna Marzullo and Helen DiPrima to sit at his table at the Northeast Republican Leadership Conference.

The women appear in ads from the Charles and David Koch-backed group Americans for Prosperity (AFP) knocking New Hampshire Democratic Reps. Carol Shea-Porter and Ann McLane Kuster on ObamaCare.

While DiPrima was unavailable, Marzullo and her husband, state GOP Vice Chair J.P. Marzullo, will attend with Brown.

Republicans see Brown as their best shot at taking down the Shaheen, whom they believe to be vulnerable because of ObamaCare’s unpopularity in the state.

In an email to the Union Leader, Brown slammed Shaheen and Senate Majority Leader Harry Reid (D-Nev.), who had charged that AFP is currently blanketing competitive states with “lies.”

"I was offended when Harry Reid took to the Senate floor to attack the character of Helen and Donna, who like millions of other Americans, were innocent victims of Obamacare's disastrous consequences. Even more outrageous was Senator Shaheen's deafening silence and her unwillingness to stand up for her constituents who were being unfairly smeared,” he said.

"Unfortunately, it wasn't all that surprising, as Senator Shaheen has consistently and reliably put the interests of liberal party leaders in Washington ahead of New Hampshire families, especially when she cast the deciding vote that made Obamacare the law of the land."
