The mother of a State Department official killed in Libya is publicly criticizing the Obama administration for not answering questions about her son's death. 

"Don't give me any baloney that comes through with this political stuff," Pat Smith told CNN's Anderson Cooper Wednesday. Her son, Foreign Service Officer Sean Smith, was one of four Americans killed at the consulate in Benghazi on Sept. 11. "Just tell me the truth, what happened, and I still don't know." 

Smith added, "The things they are telling me are just outright lies." U.N. Ambassador Susan Rice, she said, told her the attack was a result of protests around an anti-Muslim video. "I don't trust you anymore," she said of the administration. "You -- I'm not going to say lied to me, but you didn't tell me and you knew." 

Republicans have criticized officials for initially tying the attack to that video; in recent days the administration has characterized the assault as a premeditated act of terrorism.  

Mitt Romney has stopped speaking about another victim of the attack, Glen Doherty, after the former Navy SEAL's mother said she didn't want her son used to disparage President Obama. Romney had met Doherty in California and used him as an example of American fighting spirit.
