SAN DIEGO -- The attorney for ex-Poway defense contractor Brent Wilkes will continue delivering his closing argument Wednesday in the defendant's trial on charges of allegedly bribing former Rep. Randy "Duke" Cunningham with cash and gifts.

Attorney Mark Geragos told the jury Tuesday that prosecutors had no case without former Wilkes' consultant Mitchell Wade, who pleaded guilty to bribing Cunningham and has yet to be sentenced.

Wade testified that pressure from Cunningham on the Defense Department meant "hundreds of thousands of dollars" for his Washington, D.C.-area consulting business and millions of dollars in defense contracts for Wilkes' company, ADCS Inc.

Geragos said Wade testified the way he did to "save his own skin."

The attorney said Wilkes spent 13 years building his small company and met government resistance at every turn.

Geragos said Wilkes is not guilty because he didn't conspire with anybody.

Also Tuesday, Assistant U.S. Attorney Sanjay Bhandari told jurors in his closing argument that Wilkes and Wade bribed Cunningham and hid the bribery in a "sophisticated and intelligent fashion" so they wouldn't get caught.

Wilkes, 53, is charged with 13 counts, including conspiracy to commit honest services wire fraud, bribery of a public official and money laundering, 10 counts of honest services wire fraud, and one count each of bribing a public official and money laundering.

He faces up to 20 years in prison if convicted.

Cunningham pleaded guilty to accepting more than $2.4 million in bribes and was sentenced to more than eight years in federal prison. He did not testify at Wilkes trial.

Bhandari told jurors that Wilkes' nephew, Joel Combs, testified that company policy at ADCS, where he worked for his uncle, was to keep Cunningham's name off meal tabs and other receipts.

"They knew what they were up to was wrong ... and they needed to hide it," the prosecutor said.

Bhandari said Wilkes pressured other congressmen besides Cunningham for support in landing millions of dollars in contracts, but it was clear that "Congressman Cunningham was an extremely important congressman for Mr. Wilkes."

Defense Department officials testified that Wilkes' seemingly close relationship with Cunningham and the defendant's actions toward securing lucrative contracts "didn't make sense," Bhandari told the jury.

"There was a sense of entitlement that Mr. Wilkes displayed," the prosecutor said.

Bhandari said Wilkes provided limousine service for Cunningham, jet boats, a jet dock, a computer, vacations, loan payments, software, a $6,000-per-night suite at a Hawaiian resort, complete with prostitutes.

Wilkes also sent Cunningham $525,000 through "designated money launderers" to help pay off a mortgage on the congressman's multi-million dollar home in Rancho Santa Fe, Bhandari told the jury.

The prosecutor said Wilkes' actions were not business as usual in Washington, D.C.

The jury is expected to get the case Wednesday morning.
