Rep. Erik Paulsen (R-Minn.) also endorsed the Florida senator ahead of Minnesota’s caucus on March 1. He said Rubio is the best candidate to unify the Republican Party and win in the general election.

“Marco understands the American Dream because he has lived it and he knows that for future generations of Americans to have a shot at that dream, we need a new-generation of conservative leadership in Washington. Marco will be that kind of leader and I’m thrilled to be supporting him,” Paulsen said in a statement.
