Story highlights "I'm sure it's blessed if the Pope drank out of it. Why not?" Brady said

The Pope's glass will reside in Brady's Pennsylvania home, and he hopes to pass it along to his grandchildren

Washington (CNN) After Pope Francis finished his speech to Congress on Thursday, a Pennsylvania congressman walked up to the rostrum and swiped the half-empty glass from which the Holy See had just sipped.

Glass in hand, Democratic Rep. Bob Brady carefully walked back to his office where he, his wife, a friend and a staffer took turns sipping the water from the glass.

Pennsylvania Sen. Bob Casey, along with his wife, mother and Rep. Joe Crawley also joined in, but stopped short of sipping from the glass. They instead dipped their fingers in and "blessed themselves," Brady said. Casey's office confirmed the moment.

"I saw the Pope drinking out of it three or four times and I thought it would be a great idea ... for me to have something of a remembrance of Pope Francis," Brady told CNN in a phone interview Friday. "I just saw the glass, I walked up and picked it up and kept it."
