There was a scavenger hunt on Capitol Hill Thursday.

Sen. Rand Paul said on Twitter in the late morning he was heading to the “secure location” where the House of Representatives’ bill to repeal and replace the Affordable Care Act was being kept. The Kentucky Republican soon became a mini-sensation on Twitter after setting off on his mission, which followed a report the bill is being kept in a dedicated reading room.

“I have been told that the House Obamacare bill is under lock & key, in a secure location,” Paul tweeted.
