Story highlights Rep. Buddy Carter said that Republican senators' "no" votes on Obamacare repeal are "extremely frustrating"

(CNN) Rep. Buddy Carter of Georgia responded to a Senate GOP colleague's vote against moving forward on several Republican health care bills by saying, "somebody needs to go over there to that Senate and snatch a knot in their ass."

Responding to a question about Sen. Lisa Murkowski's "no" vote from MSNBC's Ali Velshi on Wednesday, he used the expression, which has Southern roots and loosely means to beat someone up in retribution.

Early Wednesday morning, President Donald Trump called out Sen. Lisa Murkowski for her vote against the GOP's effort to repeal Obamacare. He tweeted, "Senator @lisamurkowski of the Great State of Alaska really let the Republicans, and our country, down yesterday. Too bad!"

Carter went on to defend the President's public criticism of a fellow Republican, saying the tweet is "perfectly fair."

Mary Carpenter, a spokesperson for Carter, said that his "comment was in no way directed towards Senator Murkowski specifically." She added: "This is a Southern phrase used frequently throughout Rep. Carter's lifetime which simply means, 'get your act together.'"
