HOLLYWOOD, Fla. -- A Hollywood flight attendant charged with multiple counts of credit card fraud says she's innocent -- but the FBI says it wants to know if the money they think she scammed went to help terrorists.

Maha Elsaai, who is a naturalized U.S. citizen from Egypt, pleaded not guilty Tuesday to committing thousands of dollars worth of credit card fraud.

Last month, FBI agents arrested Elsaai, who was a flight attendant for Planet Air Charters, at her Hollywood home.

Agents went through her trash, collecting evidence that they say links Elsaai to $200,000 in credit card fraud.

Her brother says he does not believe his sister did anything wrong.

"I don't think she did all this because where is the money? That is the question," said Ashrraf Elsaai.

The FBI, too, wants to know where the money is.

According to the indictment, agents started investigating Elsaai after a witness in another case told them Elsaai had made statements implying the Sept. 11 terrorist attacks were justified.

When agents checked further into her background, agents said they found Elsaai's name in FBI files just one month after the attacks, when according to the indictment, "Elsaai had numerous credit cards and held views that were hostile to the United States."

Her brother, though, says that just can't be true.

"My sister, she's been here 16 or 17 years. She loves America," Ashrraf Elsaai said. "She's been working in the airline business for 10 years."

A source close to the investigation told Local 10 that agents want to know if any of the money involved in the credit card fraud was used to help fund the 9/11 hijackers, many of whom also lived for a time in Hollywood.

Ashrraf Elsaai said his sister was in Washington shortly after the attacks and was horrified by what happened.

"She called me on the phone. She told me, 'These guys are animals,'" he said. "'They did something bad really' -- that was her comment."

The FBI is refusing to answer any questions about the case. Maha Elsaai continues to be held without bond.
