Recently re-elected REP. JESSE JACKSON JR. resigned from Congress after suffering “several serious health issues.”

In July, The ENQUIRER reported “doctors diagnosed Jesse Jr. with bipolar disorder,” according to a source.

Now, Jackson, 47, has bowed out of Congress saying, “For 17 years I have given 100% of my time, energy, and life to public service. However, over the past several months, as my health has deteriorated, my ability to serve the constituents of my district has continued to diminish. Against the recommendations of my doctors, I had hoped and tried to return to Washington and continue working on the issues that matter most to the people of the Second District. I know now that will not be possible.”

“The constituents of the Second District deserve a full-time legislator in Washington, something I cannot be for the foreseeable future,” he wrote in his resignation letter.

“My health issues and treatment regimen has been incompatible with service in the House of Representatives. Therefore, it is with great regret that I hereby resign as a member of the United States House of Representatives, effective today, in order to focus on restoring my health.”

Jesse Jr. is the son of civil rights leader the Rev. Jesse Jackson.

This summer the congressman’s office announced he was “receiving intensive medical treatment at a residential treatment facility for a mood disorder.” A few weeks later, his office said he was undergoing an “extensive inpatient evaluation for depression and gastrointestinal issues” at the Mayo Clinic.

As The ENQUIRER reported, some insiders point the finger of blame squarely at a gastric bypass operation the politician underwent in 2004 because it can restrict the intake of nutrients.
