(CNN) - The National Republican Senatorial Committee will no longer support Rep. Todd Akin of Missouri in his U.S. Senate bid, a source from the group told CNN Senior Congressional Correspondent Dana Bash on Monday.
It was communicated to the congressman that the NRSC will be pulling out if he decides to stay in the race, the source said one day after the Senate candidate sparked a firestorm by claiming that "legitimate rape" rarely resulted in pregnancy.

Multiple Republicans have distanced themselves from Akin since he originally made the comment, and Sen. Scott Brown of Massachusetts called on him to step down from his position as GOP nominee.
Akin apologized for the comment Monday, saying he misspoke.
"I made that statement in error. Let me be clear. Rape is never legitimate. It's an evil act, and it's committed by violent predators," Akin said on Mike Huckabee's radio show. "I used the wrong words in the wrong way. What I said was ill conceived and it was wrong."
The NRSC said it currently has $5 million reserved to back the Republican candidate against incumbent Democratic Sen. Claire McCaskill. Republicans have pointed to the seat this year as a possible pick-up for the GOP as the party tries to retake the Senate majority.
Following Akin's comments, however, a source from the NRSC said that if Akin remained in the race, it "could put the majority at risk."
In a statement earlier Monday, Sen. John Cornyn of Texas–who also chairs the NRSC–suggested the congressman "carefully consider" his next step.
"Congressman Akin's statements were wrong, offensive, and indefensible," Cornyn said in a statement. "I recognize that this is a difficult time for him, but over the next twenty-four hours, Congressman Akin should carefully consider what is best for him, his family, the Republican Party, and the values that he cares about and has fought for throughout his career in public service."
In an interview with WMUR Monday, Mitt Romney echoed Cornyn's sentiments, according to a tweet from the station's political director, Josh McElveen:
"@MittRomney on if Akin should end senate bid- 'he should spend 24 hours considering what will best help the country at this critical time.'"
Akin has long been known for his social conservative values. The congressman captured a win in Missouri's three-way Senate primary earlier this month, beating out businessman John Brunner and former state treasurer Sarah Steelman despite falling behind in the polls just days before the contest.
On Huckabee's radio show Monday, Akin said he had not been specifically told to exit the race.
"No one has called me and said, 'I think you should drop out.' No one has said that. I gather people are saying that in the media, but they didn't specifically call me and tell me that," Akin said.
