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 ObamaReport: Trump tweeted 470 times in first 99 days Biden schedule sets off 2020 speculation Obama makes 0K for speech at A&E event: report 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.
