We posed the question earlier this week: Can Congress behave itself when the pope visits?

Appears there is some real concern that grown adults won’t be able to restrain themselves from acting like adolescents at a One Direction concert the moment Pope Francis enters the chamber next week.

So on Thursday, lawmakers received a letter signed by House and Senate leaders requesting decorum. (Yes, really, this had to be asked.)

“Out of respect for the Pope’s schedule and the expectation of a timely address, we respectfully request that you assist us by refraining from handshakes and conversations along and down the center aisle…,” read the letter, signed by House Speaker John Boehner, Senate Majority Leader Mitch McConnell, House Minority Leader Nancy Pelosi and Senate Minority Leader Harry Reid.

More information on “dignitary protocols” would be available on their congressional internal Web sites. We’re hearing from several Senate sources that it’s not posted yet. Well, these things take time when there’s so much to cover. (No selfies. No fist pumping. No cheering. No, not even a hearty, “amen.”)

Such little faith in members of Congress.
