Joseph Percoco, a former top aide to Gov. Andrew Cuomo, wants you to know he’s sorry for the actions that led to his conviction for soliciting more than $300,000 in bribes from two companies with business before the state.

He said so in a letter late Thursday to U.S. District Judge Valerie Caproni of the Southern District of New York–who is set to sentence him next Thursday, Sept. 20–months after a jury convicted him on federal bribery charges in March.
