WASHINGTON (CNN) -- Former New York City Mayor Rudy Giuliani announced his Massachusetts leadership team Thursday, the same day former Bay State Gov. and presidential candidate Mitt Romney plans a major fundraising gala in Boston.

Former Massachusetts Gov. Paul Cellucci will head up Giuliani's Bay State leadership team that includes a majority of the current Republican state senators as well as other Massachusetts Republicans, according to a statement from Giuliani's presidential exploratory committee.

Brian Cresta, former chair of the Massachusetts Republican State Committee, Michel Knapik, a state senator, Bran Lees, a former senate minority leader, Bruce Tarr, the current assistant senate minority leader, and Richard Tisei, the current senate minority leader make up Giuliani's bay-state team.

"It's an honor to have such valued Republican leaders in Massachusetts supporting Mayor Giuliani," Giuliani spokeswoman Katie Levinson said in the statement.

The announcement of Giuliani's leadership team comes a day after former Massachusetts GOP Gov. Jane Swift, Romney's direct predecessor, had agreed to throw her support behind another contender for the Republican presidential nomination, Arizona Sen. John McCain.
