The son of U.S. Sen. Rand Paul was arrested for underage drinking and disorderly conduct after being arrested at Charlotte's Douglas International Airport.
William Hilton Paul was arrested following a flight from Kentucky to North Carolina, according to the Mecklenburg County Sheriff's Office in Charlotte.
Authorities did not say whether William Paul, of Bowling Green, Kentucky, was believed to have been drinking on the airplane or at the airport.
"Sen. Paul is a national public figure and subject to scrutiny in the public arena."
"However, as many parents with teenagers would understand, his family should be afforded the privacy and respect they deserve in a situation such as this."
William Paul was charged with three misdemeanor offenses: disorderly conduct at an airport, being intoxicated and disruptive and consuming beer and wine underage.
He has maintained a fairly low profile, appearing at a handful of campaign events alongside his father, who was elected to the U.S. Senate in 2010.
Rand Paul has publicly said he is interested in running for president in 2016.
Rand is the son of retiring Rep. Ron Paul of Texas, who was the 1988 libertarian candidate for president, and who made bids in 2008 and 2012 for the GOP nomination.
Under the mantle of libertarian conservatism, Ron Paul galvanized a strong contingent of loyal support; his son may lay claim to that mantle in 2016.
