NEW YORK (AP) — Closing arguments are scheduled to begin Tuesday in the bribery trial of a former top aide to Democratic Gov. Andrew Cuomo.

Defense lawyers presented witnesses over three days to refute a month of evidence from prosecutors aimed at convincing jurors in Manhattan federal court that Joseph Percoco accepted more than $300,000 in bribes from three businessmen to treat them favorably.

Lawyers for the 48-year-old Percoco and the businessmen have maintained that they acted legally and appropriately.

On Monday, all four defendants confirmed to Judge Valerie Caproni that they had decided not to testify.

Closing arguments likely will focus on the credibility of Todd Howe, a lobbyist who was arrested after admitting he had violated his cooperation agreement with the government.
