Rep. Jesse Jackson Jr. (D-Ill.) submitted a letter announcing his resignation from Congress to Speaker John Boehner (R-Ohio) on Wednesday, according to a Boehner aide.
"For seventeen years I have given 100 percent of my time, energy, and life to public service," Jackson wrote.
"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 of the people of the Second District. I know now that will not be possible."
Jackson's resignation comes amid reports that he is being investigated by the Justice Department for allegedly misusing campaign donations to redecorate his home.
