Romney to endorse Rubio in 2016 Republican White House race: report
Former U.S. Republican presidential nominee will endorse Marco Rubio in the race for the party's presidential nomination, Huffington Post reported on Sunday.
The endorsement came on the heels of Rubio's second-place finish in Saturday night's primary in South Carolina, where he edged out rival Ted Cruz for the No. 2 slot, the website reported, citing unidentified Republican sources.
