The House floor erupted Thursday shortly before Congress adjourned for the week when Republican Rep. Jason Smith yelled a potentially racially charged remark across the aisle as Democratic Rep. Tony Cárdenas was at the podium.

“Go back to Puerto Rico!” the Missouri congressman shouted, punctuating a stream of Republican whooping and hollering at the Democratic majority for initially rejecting their request to redo a vote on a continuing resolution to reopen shuttered agencies through Feb. 28.

Democrats had called for a voice vote on the CR, as is typical with most votes, and Republicans wanted a roll call vote to show most of their members objected to the measure. Democrats said they never requested one, but some Republicans disputed that.

Afterward, House Majority Leader Steny Hoyer noted the Puerto Rico comment that he said was directed at Cárdenas of California.
