Paul, who is a Kentucky senator, stands out from the Republican pack because of his comparatively libertarian views as the party is known for its mostly conservative views.
United States senator, Rand Paul has announced his 2016 presidential bid under the Republican ticket, becoming the the second Republican to enter the presidential contest.
According to a message on his website, Paul said:
"I am running for president to return our country to the principles of liberty and limited government"
According to BBC, Paul, who is a Kentucky senator, stands out from the Republican pack because of his comparatively libertarian views as the party is known for its mostly conservative views.
He was first held elected into office when he rode a wave of Tea Party popularity to the US senate in 2010, quickly drawing attention when he spoke for more than 12 hours in protest about President Barack Obama's drone policy and the nomination of John Brennan to lead the CIA.
Paul is an ophthalmologist and the son of Ron Paul, who ran for president several times.
He is anti-surveillance and anti-drone, but conservative on same-sex marriage and abortion and also has less than cordial relations with senior party figures like John McCain and Mitch McConnell.
He is also expected to run a very tech-savvy campaign that could create appeal to new Republican demographics, like young voters.
Other Republicans who are expected to battle for the Republican ticket include Florida Governor Jeb Bush, Wisconsin Governor Scott Walker and senator Ted Cruz who has already formally declared his presidential bid.
