DETROIT -- A young Muslim woman said she and another woman were refused seats directly behind Barack Obama -- and in front of TV cameras -- at a Detroit rally because they wear head scarfs.

Hebba Aref said Wednesday that she and Shimaa Abdelfadeel were among 20,000 supporters who gathered to see Obama on Monday at the Joe Louis Arena when the groups they were with were separately invited by Obama campaign workers to sit behind the podium. But Aref said the campaign workers told members of both parties in separate discussions that women wearing hijabs, the traditional Muslim head scarves, weren't included in the invitation and couldn't sit behind the podium.

SoundOff: Head Scarf Controversy

Aref, a 25-year-old lawyer, said a member of her group was told by a campaign worker that she could not invite Aref because of "a sensitive political climate."

Her brother, Sharif Aref, attended the rally with Hebba.

He told Local 4 the family is deeply hurt and hopes Obama personally apologizes.

“We’re not demanding anything. We’re just asking politely for Barack Obama to take some sort of accountability and just apologize,” said Sharif Aref.

Sharif said he still supports the Illinois senator but was struck by the hypocrisy at the Joe on Monday.

“I was kind of saddened by it. To hear Barack Obama preach hope and change while, at the very same event, you have discrimination taking place. I still intend to vote for him and I don’t think he knew what was going on, I don’t think he had bad intentions, I just think he needs to be aware,” said Sharif Aref.

Obama spokesman Bill Burton issued a statement saying such actions are "not the policy of the campaign."

"It is offensive and counter to Obama's commitment to bring Americans together and simply not the kind of campaign we run. We sincerely apologize for this behavior," the statement read.

Aref said she replied by thanking Burton, but requested Obama apologize directly to her and Abdelfadeel, as well as invitations to sit behind him at a future campaign event. Obama spokeswoman Amy Brundage said she was looking into the request.

"He needs to take the matter seriously and send a strong message against any kind of discrimination," Aref said.

A message was left Wednesday morning by The Associated Press for Abdelfadeel.

Presidential campaigns routinely invite audience members they believe will enhance the image their candidate wants to convey on TV to stand behind the candidate at rallies.

Aref, who was born in the United States to Egyptian immigrants, said she had defended Obama during the primaries against a constant drumbeat of rumors that he was Muslim. Obama, a Christian, has said his grandfather was Muslim who converted to Christianity.

Obama also has been careful in denouncing the links, noting that some rumors about him also have been insulting to Muslims.

"I don't want to be called something I'm not, but I felt like ... everyone was treating this accusation of being Muslim as though it were some sort of crime or sin," Aref said.

She was grateful that the group she was with at the rally declined the invitation to take seats behind Obama after she was refused.

Still, she said, it was difficult to hear Obama's message of unity among races.

"As he's saying it, I'm thinking, `Well, wait a minute, I was obviously ... profiled and discriminated against an hour ago."'
