his campaign. In that election a blogger accused Stone of responsibility for the Kerry–Specter campaign materials which were circulated in Pennsylvania. Such signs were considered controversial because they were seen as an effort to get Democrats who supported Kerry to vote for then Republican Senator Arlen Specter in heavily Democratic Philadelphia. During the 2004 general election, Stone was accused by then-DNC Chairman Terry McAuliffe of forging the Killian memos that led CBS News to report that President Bush had not fulfilled his service obligations while enlisted in the Texas Air National Guard. McAuliffe cited a report in the New York Post in his accusations. For his part, Stone denied having forged the documents. In 2007, Stone, a top adviser at the time to Joseph Bruno (the Majority Leader of the New York State Senate), was forced to resign by Bruno after allegations that Stone had threatened Bernard Spitzer, the then-83-year-old father of Democratic gubernatorial candidate Eliot Spitzer. On August 6, 2007, an expletive-laced message was left on the elder Spitzer's answering machine threatening to prosecute the elderly man if he did not implicate his son in wrongdoing. Bernard Spitzer hired a private detective agency that traced the call to the phone of Roger Stone's wife. Roger Stone denied leaving the message, despite the fact that his voice was recognized, claiming he was at a movie that was later shown not to have been screened that night. Stone was accused on an episode of Hardball with Chris Matthews on August 22, 2007, of being the voice on an expletive-laden voicemail threatening Bernard Spitzer, father of Eliot, with subpoenas. Donald Trump is quoted as saying of the incident, "They caught Roger red-handed, lying. What he did was ridiculous and stupid." Stone consistently denied the reports. Thereafter, however, he resigned from his position as a consultant to the New York State Senate Republican Campaign Committee at Bruno's request. In January 2008, Stone founded Citizens United Not Timid, an anti-Hillary Clinton 527 group with an intentionally obscene acronym. Stone is featured in Boogie Man: The Lee Atwater Story, documentary on Lee Atwater made in 2008. He also was featured in Client 9: The Rise and Fall of Eliot Spitzer, the 2010 documentary of the Eliot Spitzer prostitution scandal. Former Trump aide Sam Nunberg considers Stone his mentor during this time, and "surrogate father". 2010–2014: Libertarian Party involvement and other political activity In February 2010,
