In closing arguments on Wednesday in the corruption trial for Joseph Percoco, a former aide to Gov. Andrew Cuomo, Percoco’s attorney made a final effort to impeach the government’s star witness in the case while portraying his client’s alleged quid pro quo as attempts to help out friends.

Percoco’s attorney, Barry Bohrer of Schulte Roth & Zabel, also used his closing arguments, which lasted most of the day and concluded late in the afternoon, to criticize certain aspects of the prosecution’s case against Percoco and his three co-defendants, including its focus on the language used in emails presented as government exhibits.
