Kentucky Republican Sen. Rand Paul's 19-year-old son — who is also frequent GOP presidential candidate and current Texas Rep. Ron Paul's grandson — was arrested on drinking charges at the Charlotte, N.C., airport over the weekend, according to police. William Hilton Paul was charged with underage drinking, disorderly conduct and being intoxicated and disruptive after getting off a flight on which police said he may have been served alcohol. Paul had just arrived on a U.S. Airways flight from Lexington, Ky., and was released on $750 bond two and a half hours after being booked into jail, according to county records. "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," Sen. Paul's office said in a statement. William Hilton Paul is scheduled to appear in court at 1 p.m. ET on Tuesday.
