Sen. Scott Brown (R-Mass.) voted with Democrats today to pass a $15 billion jobs bill.

Brown made headlines on Monday when he voted to end a Republican filibuster of the legislation. Today he broke GOP ranks to vote for the legislation itself.

"This jobs bill is far from perfect, and ideally would include deeper and broader tax cuts," Brown said in a statement. "I supported this measure because it does contain some tax relief that will help Massachusetts businesses put people back to work."

Brown said he "reserves the right" to vote against the legislation if it changes dramatically during negotiations with the House.

"Right now, this is a tax-cutting bill. But if it comes back to the Senate full of pork, waste, fraud and abuse, I reserve the right to vote against it," he said.
