Diane Horning, mother of 26-year-old 9/11 victim Matthew Horning, spoke to Current TV's Keith Olbermann last night about her meeting with Attorney General Eric Holder on the investigation into whether employees of News Corporation hacked into the voicemails of 9/11 victims.

"We asked for a timeline but [Holder] was not able to give us that and said this is the preliminary stage," she told the progressive news host. "He also said they broke with tradition here because this is the first time they actually sat down and spoken to people about a preliminary stage of an investigation. He just felt that the sensibilities were such that he needed to do that."

She called the allegations "disturbing" and "serious," but did not attempt to place blame on the company.

Holder staged the meeting yesterday, inviting about 10 people whose relatives died during the attacks. An official speaking on the condition of anonymity said that if the Justice Department can prove that victims' phone messages were hacked, the perpetrators may face up to five years in prison and other punitive damages.
