McConnell grew increasingly angry as Franken made fun of him before a crowded public gallery and Senate aides lining the chamber walls. Senate aides said they were shocked that Franken would flout the decorum of the chamber during such a solemn occasion.

A spokeswoman for Franken did not immediately return requests for comment.
