Lee and Lott celebrate Seersucker Thursday

Sen. Mike Lee (R-Utah) and his staff changed out of their usual Capitol Hill suits for ones made out of seersucker this week.

They joined former Sen. Trent Lott (R-Miss.) in celebrating what has become an annual Washington tradition — seersucker Thursday.

It's the second year in a row the freshman senator has taken part in the event, which Lott started in 1996.

The former Senate majority leader joined Lee and his staff for a group photo to commemorate the event.

Every June, lawmakers and staff pick a Thursday to wear the snazzy blue-and-white pinstripes. And, given Washington's heat wave, the lightweight fabric was sure to be a relief from the usual dark fabrics seen in the halls of Congress.
