The star of CSI: Miami had a very covert investigation to conduct on Tuesday: exploring Nationals Park.
Omar Benson Miller, who plays Walter Simmons on the show, came out to the park to watch the Nationals take on the Astros.
The star was in town to lobby for America for the Arts, a group headed up by Alec Baldwin, which advocates for federal funding for the arts in schools.
After a day of congressional meetings, Miller, a self-proclaimed baseball fanatic, chatted with players and watched both teams take BP.
