WASHINGTON — Sen. David Vitter, a staunch conservative who wants to break up big banks and overhaul the Federal Housing Administration, will be singing a different tune this weekend — namely that of pop idol Justin Bieber.

The Louisiana Republican is cutting loose at Bieber's Saturday evening performance at the Verizon Center in downtown Washington and, for $1,000 a head (or per political action committee), Vitter supporters can relive their youth in a designated suite with the lawmaker. Three of Vitter's children, Jack, age 11, and his 16-year-old twin daughters, Airey and Lise, will also be in attendance.

The event is being hosted by a campaign committee, David Vitter for Senate. Vitter, a member of the Senate Banking Committee, is up for reelection in 2016, though rumors about a potential run for Louisiana governor in 2015 continue to swirl.

This is hardly Vitter's first unusual campaign outing. In May, he was part of a $5,000-per-person "Louisiana Bayou Weekend" that featured an alligator hunt.
