Prosecutors urged jurors on Friday to focus on two questions at the corruption trial of former Virginia Gov. Bob McDonnell and his wife, Maureen: Why did a businessman give the couple more than $165,000 in gifts and loans, and why did the McDonnells accept? The answer, prosecutor David Harbach said in his closing argument, was a 'corrupt understanding.' The McDonnells needed money because they were badly in debt, and he said they were willing to undertake official acts to help former Star Scientific Inc. CEO Jonnie Williams promote his tobacco-based supplement, Anatabloc. 'That is bribery. That is corruption ... the real thing,' Harbach said. Scroll down for video . In closing arguments, prosecutors argued that former Virginia Gov. Bob McDonnell accepted huge cash gifts because he was in a pile of debt . The McDonnells are charged in federal court in a 14-count indictment and could face decades in prison if convicted. They are being tried together, but have their own attorneys, who will give their closing arguments later Friday. Harbach said the only reason Williams did not get the state-backed research he wanted was because a McDonnell aide 'shut it down.' The 'polite no' did not come from McDonnell, he said. 'That's because he was on the Jonnie Williams gravy train, and he and Jonnie Williams had a deal: Do what you can when opportunities arise and I'll keep paying,' Harbach said. He said it doesn't matter that McDonnell failed to help Williams get a state grant for research studies. 'The corrupt deal is why he's guilty,' Harbach said. The five-week, soap opera-like trial aired the McDonnells' dirty laundry as family members and those in the former first couple's inner circle testified about their fights, crumbling marriage and financial troubles.

McDonnell denied knowing Williams had paid for such expensive dresses. The former governor wasn't on the shopping spree, but did sit next to Williams later that day at an event.
