U.S. Republican presidential candidate Rand Paul suspended his 2016 campaign on Wednesday, he said in a statement two days after the Iowa caucuses.
The U.S. senator from Kentucky, a libertarian-leaning candidate, finished in fifth place in Iowa with 4.5 percent.
"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," Paul said in a statement.
