Senator Rand Paul, a possible candidate for president in 2016, is headed to New Hampshire again.
On Thursday night, Paul will attend a gathering of Generation Opportunity, a conservative group with links to billionaires Charles and David Koch.
On Friday, he'll headline a Republican party "Unity Breakfast" to rally the party after this week's primary.
Later Friday, he'll endorse Scott Brown for U.S. Senate. Brown is the former senator from Massachusetts who moved to New Hampshire in December and won Tuesday's primary to set up a run against incumbent Democrat Jeanne Shaheen.
Paul, whose father Ron Paul has run for president three times, has visited the key early-voting state several times over the past two years. He's among a number of Republicans seen as potential presidential candidates in 2016.
