Federal prosecutors recommend a judge sentence Robert Menendez, the former New Jersey senator found guilty of corruption offenses, to 15 years in prison.

“This case is the first ever in which a Senator has been convicted of a crime involving the abuse of a leadership position on a Senate committee” reads the 108-page prosecution submission filed by the U.S. Attorney’s Office for the Southern District. “It is the first ever in which a Senator—or any other person—has been convicted of serving as a foreign agent while being a public official.”
