NEW YORK The FBI has for the first time released materials from its files on former New York Mayor Ed Koch.

The papers posted on an FBI website Tuesday don't offer any bombshells. They focus mostly on an investigation of an alleged plot in 1977 to circulate fake letters that tried to paint then-Congressman Koch as a racist.

A summary of an FBI interview says a suspect in the case denied any involvement. But he also told agents he hated Koch and would beat him up if he got the chance.

Koch served three terms as mayor from 1978 to 1989. He won a national reputation with his feisty style and his trademark question, "How'm I doing?"

He died earlier this year at age 88.
