U.S. District Judge Richard Berman of the Southern District of New York on Monday ordered a last-minute adjournment of former U.S. Rep. Stephen Buyer’s sentencing on insider trading charges, citing a potential conflict of interest issue that came to light in the days leading up to the scheduled proceeding.

Berman said Buyer’s defense counsel, Orrick Herrington & Sutcliffe partner Henry Asbill, informed the court that Orrick also represents T-Mobile.
