Former New York Congressman Anthony Weiner will be released from prison three months ahead of schedule due to good behavior, the New York Daily News reported Monday.

Weiner, who is being held at the Federal Medical Center, Devens in Massachusetts, is set for release on May 14, 2019. FMC Devens is one of two federal prisons that offer a residential treatment program for sex offenders.

Weiner pleaded guilty to transferring obscene material to a girl he knew to be 15 years old in May 2017, and was sentenced to 21 months in prison that September.

The crime also tarnished Hillary Clinton’s presidential campaign. The search warrant obtained by the FBI and the Southern District of New York for Weiner’s laptop led authorities to thousands of emails between Clinton and his wife Huma Abedin, a longtime Clinton aide. Abedin has since filed for divorce.

Former FBI Director James Comey wrote a letter informing Congress of new emails potentially pertinent to Clinton’s use of a private server days before the election.
