The shadow of the Bat will follow Ben Affleck no matter where he goes, even if it’s in the chambers of the United States Senate.

Affleck, who will play Batman in Batman Vs. Superman: Dawn of Justice, made a reference to the Dark Knight while speaking before the U.S. Senate earlier this week. In his opening statement on the importance of diplomacy, Affleck addressed U.S. Senator Patrick Leahy as his “Batman co-star.” And no, the Senator isn't about to join the Justice League. Leahy will make a cameo appearance in Dawn of Justice next year.

As an avid fan of the Caped Crusader, Leahy’s Batman film resume is actually longer than Affleck’s. Leahy cameoed in both The Dark Knight and The Dark Knight Rises, making him one of Washington’s biggest geeks.

You can see the Bat-bros address each other at the 1:30 mark.
