DOVER, Del. — A federal judge is refusing to delay the trial of four former top executives of Wilmington Trust who are facing criminal bank fraud charges.

While refusing to delay next Tuesday’s scheduled opening statements, the judge on Friday did request that Federal Reserve officials provide documents subpoenaed by Wilmington Trust as soon as possible. But he said he was not convinced that Wilmington Trust needs the documents to prepare its opening statement.

Former Wilmington Trust president Robert Harra Jr., former chief financial officer David Gibson, former chief credit officer William North and former controller Kevyn Rakowski are charged with fraud, conspiracy and making false statements to federal regulators.

Prosecutors say the defendants hid the truth about the bank’s deteriorating commercial real estate loan portfolio before its collapse in 2011.
