NEW YORK - Former Governor Bobby Jindal did something he said he wouldn't, he endorsed a Republican in the presidential primary. Jindal endorsed U.S. Senator Marco Rubio Friday evening on Fox News.

Rubio responded on Twitter.

.@BobbyJindal is one of the smartest people in American politics. We're incredibly excited to have him on the team.

Jindal announced his candidacy for president last June ending years of speculation that he would run. He dropped out of the Iowa caucuses in November when his fundraising dropped off.

At the time, Jindal said he would not endorse a candidate in the primary preferring to wait until after the Republican Convention this July.
