FBI officals confim that former Senate Minority Leader John Sampson is un custody after turning himself into federal officials earlier this morning on public corruption charges.

Several news outlets reported over the weekend that Sampson was “Senator #1″ in the recently released sentencing document for former Senator Shirley Huntley, who plead guilty to stealing taxpayer money through a non-profit organization she set up. The sentencing document revealed that Huntley wore a wire to obtain evidence against Sampson, and two unknown lawmakers, for the FBI.

According to various reports, Sampson is expected to be charged with obstruction of justice.

We’ll obviously have more on this throughout the day.

Update: United States Attorney Loretta E. Lynch will hold a press conference at 11am to announce the unsealing of an indictment in a criminal case against a New York State elected official. She does not specifically mention Sampson but we are told by FBI sources that it will be about him.
