After suffering a defeat in last month’s primary, Sen. Bill Cassidy (R-LA) hosted his last Senate Seersucker Day, leaving the beloved bipartisan tradition without a Republican leader. 

Senators and staff celebrated the 13th annual bipartisan Seersucker Day on Thursday, just weeks after Cassidy was ousted as President Donald Trump’s hand-picked candidate, Rep. Julia Letlow (R-LA), advanced to the runoff. Cassidy’s departure could lead to increased partisanship on Capitol Hill.
