WASHINGTON — Federal authorities investigating the activities of political extremist Lyndon H. LaRouche Jr. and his organization obtained handwriting samples voluntarily from LaRouche on Friday, the FBI said.
At the same time, law enforcement sources said the treasurer of LaRouche's 1984 presidential campaign has been subpoenaed in connection with the inquiry.
FBI Agent Jim Mull in Alexandria, Va., said LaRouche "did come down today to have handwriting exemplars taken." He refused to say why the handwriting samples were sought.
Sources close to the investigation said investigators wanted examples for analysis and comparison to internal memorandums and notes seized as evidence when authorities raided LaRouche's headquarters in Leesburg, Va., on Oct. 6.
