(CNN) - The newest member of the Senate will soon hit the 2010 campaign trail for Arizona Sen. John McCain.
A McCain source confirms Sen. Scott Brown, R-Massachusetts, will campaign with the 2008 Republican presidential nominee in early March. McCain is facing a primary challenge from former Rep. J.D. Hayworth.
Brown rocketed to stardom in the Republican Party after scoring an upset victory in the Massachusetts special Senate election last month to fill the seat of the late Sen. Edward Kennedy. He was sworn into the chamber Thursday afternoon.
Former Republican vice presidential nominee Sarah Palin will also hit the campaign trail for McCain at the end of March.
