Mother of State Dept. Official Killed in Libya Attack Says White House Has Been Telling Her 'Outright Lies

The mother of one of the Americans killed in the deadly terrorist attack on the U.S. Consulate in Benghazi wants answers about her son's death -- which really doesn't sound like too much to ask.

Instead, she says the Obama administration has been stonewalling; and one month later, she is still waiting for the answers that were promised to her. In fact, the administration has told her "outright lies" about the Libya assault, she said.

Pat Smith, the mother of Sean Smith, a State Department official killed in the Libya attack, told CNN's Anderson Cooper on Wednesday that President Barack Obama, Secretary of State Hillary Clinton and Vice President Joe Biden told her they would tell her the truth about what happened to her son.

"They promised me. I told them please, tell me what happened. Just tell me what happened," she said. "I told them don't give me any bologna – you can keep your political stuff. Just tell me the truth. And I still don't know. In fact, today I heard that he died of smoke inhalation."

"You don't know the cause of death?" Cooper asked, visibly surprised.

"No, I don't," Smith replied. "I look at the TV and I see bloody hand prints on walls thinking, is that my son's? I don't know. They haven't told me anything."

Smith also said the Obama administration has been telling her "outright lies" about the attack. She revealed that U.S. Ambassador Susan Rice and other senior officials told her that the attack occurred because of the anti-Muslim YouTube video that was originally blamed for the assault.

"In fact, all of them did. All of them did," she added. "Leon Panetta actually took my face in his hands like this and he said, 'trust me. I will tell you what happened.' And so far, he's told me nothing. Nothing at all. And I want to know."

Smith also recounted her interaction with President Obama himself at a reception.

"I cried on Obama's shoulder and then he kind of looked off into the distance," Smith said. "So that was worthless to me. I want a note for God's sake."

"You deserve answers," Cooper agreed.

The investigation into the attack on the U.S. consulate in Benghazi last month, where Smith was killed along with three other Americans, is ongoing. The House Oversight and Government Reform Committee held a special hearing on Wednesday to address the attack.
