Barack Obama said in a statement Thursday he has "reached out" and offered his personal apology to the two Muslim women who said they were refused seats behind the Democratic candidate at a Detroit rally because they were wearing head scarves.

The two women were given different explanations for why they were refused seats at the Monday rally, according to an article in The Politico, but Obama volunteers said it had to do with the hijabs they were wearing.

One of the women, Hebba Aref, said a volunteer told the group she was with she could not sit behind the podium -- in full view of TV cameras -- because of "a sensitive political climate."

Obama's campaign apologized in a statement Wednesday and said the volunteers' actions were "not the policy of the campaign."

Obama repeated in his statement Thursday that "the actions of these volunteers were unacceptable and in no way reflect any policy of my campaign."

He said was able to speak with Shimaa Abdelfadeel, the other woman denied a seat behind the podium, and "expressed my deepest apologies for the incident that occurred with volunteers at the event in Detroit."

"I take deepest offense to and will continue to fight against discrimination against people of any religious group or background. Our campaign is about bringing people together, and I'm grateful that Ms. Abdelfadeel accepted our apology and I hope Ms. Aref and any who were offended accept my apology as well.”
