Washington ? Show me some civility, Republicans cried Friday after a Missouri congressman speaking on the House floor was caught on microphone apparently cussing out a fellow Missourian.

Armed Services Committee Chairman Ike Skelton, D-Mo., had just finished addressing his Republican colleague Todd Akin on Thursday.

Skelton then turned to the side and muttered “stick it up your a–.”

The comment was just audible on the C-SPAN tape of the proceedings and was not included in the Congressional Record, the official record of speeches on the House and Senate floor.

Skelton’s spokeswoman, Jennifer Kohl, said the comment was not intended to be broadcast and was “said out of frustration in the heat of debate.”

She said Skelton, a veteran lawmaker known for working well with Republicans, planned to apologize to Akin.

The dispute arose over opposition from Akin and other Republicans to inclusion in a major defense policy bill of a provision extending federal hate crimes law to include violence against gays.
