Prosecutors say 64-year-old Harold Goldstein got the maximum sentence Monday for violating the terms of his supervised release.

Goldstein was sentenced to seven years in federal prison in 2003 for using the name of a Northern California attorney to represent clients in court. He was also convicted of mail fraud for sending solicitation letters to inmates.

U.S. Attorney's Office spokesman Thom Mrozek says Goldstein again started claiming he was a lawyer only days after he was released on May 1.
