Both face maximum penalties of several years in prison; he also faces hundreds of thousands of dollars in fines and forfeitures. But the government did not immediately release the text of its plea agreements. Such agreements almost invariably call for prosecutors to recommend sentences below the maximum.
The son of a famed civil rights leader, Jackson, a Democrat, entered Congress in 1995 and resigned last November. Sandi, as she's known, was a Chicago alderman, but resigned last month amid the federal investigation.
Jackson used campaign money to buy a $43,350 gold-plated, men's Rolex watch and $9,587.64 on children's furniture, according to court papers filed in the case. His wife spent $5,150 on fur capes and parkas, the document said.
"I offer no excuses for my conduct, and I fully accept my responsibility for the improper decisions and mistakes I have made," the ex-congressman said in a written statement released by his lawyers. "I want to offer my sincerest apologies ... it is my hope that I am remembered for things that I did right."
Several messages left with Jackson's father, the voluble civil rights leader Jesse Jackson, were not returned Friday. The elder Jackson has often declined to comment about his son's health and legal woes over the past several months.
The government said, "Defendant Jesse L. Jackson Jr., willingly and knowingly, used approximately $750,000 from the campaign's accounts for personal expenses" that benefited him and his co-conspirator, who was not named in the one-count criminal information filed in the case. The filing of a criminal information means a defendant has waived the right to have a grand jury consider the case; it is used by federal prosecutors when they have reached a deal for a guilty plea.
