U.S. Rep. Jesse Jackson Jr. reacted Saturday night to news that he's under investigation by the House Ethics Committee.
The committee is looking into Jackson's involvement in trying to be appointed to now-President Barack Obama's seat in the U.S. Senate.
Jackson has admitted he wanted to be appointed to the Senate, but he denies allegations that he sent emissaries to offer campaign cash to then-Gov. Rod Blagojevich in exchange for the seat.
"Let me be clear. I believe in the American system of justice," Jackson told a gathering of the NAACP in Kankakee. "The process is continuing, but in the end I believe I will be vindicated."
Last Thursday, the former governor's brother, Robert Blagojevich, announced he'd sent a letter to the Ethics Committee, offering to testify against Jackson. Robert Blagojevich claims two men came to him, claiming to represent Jackson, and offering millions in exchange for appointing him senator.
