Paul Kevin Curtis, who was charged and then cleared of sending poison-laced letters to President Barack Obama and others, has filed a defamation lawsuit against the current suspect in the case.
The lawsuit was filed Wednesday in Alcorn County Circuit Court.
It says James Everett Dutschke framed Curtis when he sent ricin-tainted letters on April 8 to Obama, U.S. Sen. Roger Wicker and Sadie Holland, a Mississippi judge.
Curtis was arrested in Corinth April 17, but the charges were dropped six days later.
Dutschke was arrested April 27 at his home in Tupelo. He denies involvement.
The lawsuit says Curtis, an entertainer and Elvis impersonator, was portrayed as a terrorist and lost income because he was "no longer marketable in his chosen field."
