CHICAGO, Ill. -- Former Congressman Jesse Jackson Jr. signed a plea deal on Friday.
Jackson was being investigated for improper use of campaign funds. His sentence is to be determined by a federal judge and he could face jail time.
He resigned from the House of Representatives on November 21, 2012. Jackson had served in Congress for 17 years.
Jackson's letter of resignation was sent to Speaker John Boehner - citing ongoing health concerns, and acknowledging a federal investigation into his use of campaign funds.
He said in his letter that: "The constituents of the Second District deserve a full-time legislator in Washington, something I cannot be for the foreseeable future".
His resignation came only 15 days after winning re-election by a sizeable margin.
