Missouri Congressman Todd Akin says heā€™s apologetic but wonā€™t bow out of the race for the United States Senate after suggesting that womenā€™s bodies can prevent pregnancies in ā€œlegitimate rapeā€ situations.

ā€œPeople do become pregnant from rape and I didnā€™t mean to imply that that wasnā€™t the case. It does happen,ā€ Akin told radio host Mike Huckabee on Monday.

He also apologized for using the phrase ā€œlegitimate rapeā€ saying that he intended to use the phrase ā€œforcible rape,ā€ a controversial term that critics say appears to exclude statutory offences and situations where the victim has been drugged.

ā€œA rape is equally tragic,ā€ Akin said Monday. ā€œAnd I made that statement in error. Let me be clear: Rape is never legitimate. Itā€™s an evil act.ā€

Akinā€™s about-face comes as many in the Republican Senate nomineeā€™s own party attempt to distance themselves from his suggestion that when it comes to pregnancy from rape ā€œthe female body has ways to try to shut that whole thing down.ā€

Republican presidential candidate Mitt Romney issued a statement Sunday, distancing his campaign from Akinā€™s comments.

"Governor Romney and Congressman (Paul) Ryan disagree with Mr. Akin's statement, and a Romney-Ryan administration would not oppose abortion in instances of rape," Romney spokesperson Amanda Henneberg said.

U.S. President Barack Obama said the comments make clear why politicians should not make health decisions for women.

"Rape is rape" Obama said, adding that making a distinction among different types of rape, "doesn't make sense to the American people and certainly doesn't make sense to me."

The six-term congressman made the comments in a Sunday interview with KTVI-TV in St. Louis. He also told the station that he understood pregnancy from rape is ā€œreally rare,ā€ citing information he gleaned from doctors.

The comments prompted both outrage and mockery, and Akin first released a statement Sunday night saying that he ā€œmisspokeā€ during the interview and has ā€œdeep empathyā€ for women who are raped and abused.

In that statement, he also said that he believes ā€œdeeply in the protection of all life and I do not believe that harming another innocent victim is the right course of action.ā€

Akin won his Republican nomination by a wide margin. During the campaign, Akin and Huckabee appeared together in television ads in which the latter, a former Arkansas governor, called Akin ā€œa courageous conservative,ā€ and a ā€œBible-based ā€œChristianā€ who ā€œdefends the unborn.ā€

The backlash against Akinā€™s interview included calls for the congressman to quit the Senate race.

Insisting that heā€™s ā€œnot a quitter,ā€ Akin said Monday he wonā€™t be taking his name off the ballot.

ā€œI donā€™t know that Iā€™m the only person in public office who has suffered from ā€˜foot in mouthā€™ disease here,ā€ said Akin, adding that he made a ā€œvery, very serious error.ā€

Akin also said no one from the Republican Party has asked him to drop out of the race.

However, at least two Republican senators, Scott Brown of Massachusetts and Ron Johnson of Wisconsin, said he should quit the campaign. As well, a source told The Associated Press that the National Republican Senatorial Campaign Committee has withdrawn $5 million in advertising that had been allocated for Missouri.

The Republicans are hoping to unseat Democratic incumbent Claire McCaskill in a tight race that could allow them to gain control of the Senate in November.

On Sunday, McCaskill issued a statement saying that it is ā€œbeyond comprehension that someone can be so ignorant about the emotional and physical trauma brought on by rape."
