US Republican Party candidate Rand Paul dropped out of presidential race on Wednesday after failure of his small-government campaign.
Paul said, "It's been an incredible honor to run a principled campaign for the White House. Today, I will end where I began, ready and willing to fight for the cause of Liberty."
Rand Paul, the US senator from Kentucky, had taken a disappointing fifth place in the Iowa caucuses on Monday with 4.5 percent of the vote. US Senator Ted Cruz finished first in Iowa, putting a dent in real estate tycoon Donald Trump's standing as front-runner to be his party's nominee.
Paul, who is also focused on winning another US Senate term, said he would continue fighting for limited government, criminal justice reform and "reasonable" foreign policy.
His withdrawal leaves 10 Republican candidates in the 2016 White House race.
