“Marco lived the American Dream, and he will ensure that each and every one of us can do the same," he added.

Tillis said he is supporting Rubio because the Florida senator “has an unmatched ability to inspire and uplift the American people."

“Through his vision of optimism and his strength of principle, Marco Rubio represents a bright future for the Republican Party and America,” Tillis added. “He has the unique capability of drawing new people into the party, which is critically important in a swing state like North Carolina."

Tillis was a key pickup for Republicans in the Senate following his election in 2014, and North Carolina, which holds its voting in the GOP primary March 15, is a big swing state.

Tillis’s endorsement follows Rubio’s second-place finish on Saturday in the South Carolina primary.
