“Affairs Of State” (*** out of four) was an engrossing political thriller about a young campaign aide (David Corenswet) who gets in way over his head in a minefield of political corruption when he begins sleeping with both the wife (Mimi Rogers) and daughter (Grace Victoria Cox) of a wealthy presidential candidate and this leads to consequences he never imagined. Crafty and twisty drama provides Rogers and co-star Thora Birch with their best roles in years and a solid starring debut for Corenswet. Adrian Grenier is also solid in a key supporting role as one of the president’s other high-powered aids.
