Kentucky Senator Rand Paul has used his official announcement on Tuesday to portray himself as a "different" Republican.
"Too often when Republicans have won, we have squandered our victory by becoming part of the Washington machine. That's not who I am."
In making his pitch for the Republican nomination, Rand Paul says he is going to overcome the Washington machine.
To do this, he's proposing setting term-limits for lawmakers, suggesting those in Congress should be limited to two-terms each.
In laying out his campaign strategy, Rand Paul is also promising to kill the NSA's controversial surveillance program if he becomes President.
"And as president on Day 1, I will immediately end this unconstitutional surveillance."
At the same time, the libertarian-leaning Senator has also laid out his thoughts on foreign policy, highlighting his position on the Iranian nuclear negotiations.
"We brought Iran to the table through sanctions that I've voted for. Now we must stay strong. That's why I've co-sponsored legislation that ensures that any deal between the U.S. and Iran must be approved by Congress."
Rand Paul is the second GOP candidate to enter into the race for the White House following Texas Senator Ted Cruz.
A string of campaign debuts are expected to be rolled out in the next couple of weeks.
Leading Republicans including former Florida Governor Jeb Bush and current Wisconsin Governor Scott Walker are widely expected to roll out bids for the Republican nomination.
On the Democrat side, former Secretary of State Hillary Clinton is still the main focus of discussion.
Clinton remains the Democrat's likely choice to try to replace Barack Obama.
Her team has already leased office space in New York.
Clinton's announcement is said to be imminent.
