Rep. Randy NeugebauerRobert (Randy) Randolph NeugebauerCordray announces he's leaving consumer bureau, promotes aide to deputy director GOP eager for Trump shake-up at consumer bureau Lobbying World MORE (R-Texas) admitted Monday that he was the lawmaker who shouted "baby killer" toward a colleague during a heated House debate Sunday.

In a statement, the Texas Republican apologized for blurting out "baby killer" during Rep. Bart Stupak's (D-Mich.) speech against a motion to recommit health reform legislation that would have reinserted more stringent restrictions on federal money being used to help purchase insurance plans that cover abortion.

"In the heat and emotion of the debate, I exclaimed the phrase, 'It's a baby killer' in reference to the agreement reached by the Democratic leadership," Neugebauer said in a statement. "While I remain heartbroken over the passage of this bill and the tragic consequences it will have for the unborn, I deeply regret that my actions were mistakenly interpreted as a direct reference to Congressman Stupak himself."

Neugebauer said he had apologized to the Michigan Democrat, who opposes abortion rights but voted for the bill after President Barack ObamaBarack Hussein ObamaAnother chance to seek the return of fiscal sanity to the halls of Congress Colombia’s new leader has a tough road ahead, and Obama holdovers aren't helping An alternative to Trump's family separation policy MORE promised an executive order on abortion.

"I have apologized to Mr. Stupak and also apologize to my colleagues for the manner in which I expressed my disappointment about the bill," Neugebauer said. "The House Chamber is a place of decorum and respect. The timing and tone of my comment last night was inappropriate."

The admission fits the profile given by Rep. John Campbell (R-Calif.) on Sunday night.

An original suspect in the incident, Campbell said that the suspect was a Texan who had been sitting behind him.
