A senior U.S. Justice Department official sent a letter to a lawyer for relatives of victims killed in the Sandy Hook Elementary School shooting, asking pointed questions about a retired FBI agent's involvement in a defamation lawsuit that led to a $1.4 billion judgment against conspiracy theorist Alex Jones. That then led to years of abuse from people who believed the shooting was a hoax, he has said. Martin sends lawyer letter asking about retired agentIn a Sept. 15 letter to Christopher Mattei, a lawyer who represents Sandy Hook families, Martin suggested he was scrutinizing Aldenberg's role in the lawsuit. “In his last gasps, Jones is once again harassing them, only now with the corrupt complicity of at least one DOJ official. It’s as disgusting as it is pathetic, and we will not stand for it.”The Justice Department said it had no immediate comment Tuesday.
