PIERRE, S.D. (AP) — Republican Marco Rubio's campaign says U.S. Rep. Kristi Noem has endorsed the Florida U.S. senator's presidential bid.

In a statement from Rubio's campaign Friday, Noem says Rubio represents the kind of "next-generation conservative leader" that puts Republicans in the best position to win back the White House.

She says Rubio stands out in the Republican field because of his ability to articulate his vision for the country.

Rubio is a first-term senator.

Noem is the second member of South Dakota's all-GOP delegation to endorse in the race. Sen. Mike Rounds has endorsed Arkansas Gov. Mike Huckabee.
