Sources: Jackson's Wife Didn't Know His Resignation Was Coming Today

CHICAGO (CBS) -- Congressman Jesse Jackson Jr's wife, Ald. Sandi Jackson (7th), was in Washington, D.C., when her husband's letter of resignation was delivered this afternoon. As CBS 2's Dorothy Tucker reports, according to multiple sources, there's a good possibility Ald. Jackson might not have known her husband was submitting his resignation today.

The last time Ald. Jackson was seen in public was on Nov. 14, as she left the Jackson home in the South Shore neighborhood.

Sources said she was in D.C. with her children today, and was out shopping with them when news of her husband's resignation was released.

Ald. Jackson hasn't made any public statements since before the election, when she attended a City Council meeting and insisted her husband would not step down.

"He is on the ballot, he is going to stay on the ballot, and I'm looking forward to him coming back to work after his re-election," she said at the time.

Not only is Congressman Jackson now leaving his office, but his resignation impacts the family's finances.

He'll be losing his $174,000 salary, and can't collect his Congressional pension until he's 62 years old, in 2027.

Ald. Jackson was her husband's campaign manager, and was paid $5,000 a month. The couple also shared offices on 71st Street and Yates Boulevard, paying $1250 a month in rent.

The cloud of a federal investigation also hangs over both of them.

Federal prosecutors have been investigating allegations Congressman Jackson improperly used campaign funds to decorate the Jackson home, and according to a recent Wall Street Journal report, the feds are also looking into whether Ald. Jackson was complicit in any possible misuse of campaign funds.
