Marco Rubio has won the Republican presidential caucuses in Washington D.C. on Saturday.
It's the third presidential contest victory for the Florida senator. Earlier this month, Rubio won the GOP caucuses in Minnesota and the party's primary in Puerto Rico.
Rubio picked up 10 delegates with his Saturday caucus win in the nation's capital. Runner-up John Kasich was just 50 votes behind Rubio, and the Ohio governor will get nine delegates.
None of the other candidates in the race won enough votes to earn any delegates.
Earlier, Rubio and Kasich suggested they may not support Donald Trump if he becomes the GOP nominee, as violence at the front-runner's rallies deepened the party's chaotic chasm.
Rubio told supporters that while he was currently sticking with his pledge to back the nominee if he wasn't the party's choice, "it's getting harder every day."
Kasich said the "toxic environment" Trump is creating "makes it extremely difficult" to support him.
