Former New Jersey Sen. Bob Menendez turned himself in to federal prison on Tuesday for an 11-year sentence after he was found guilty on bribery and corruption charges.

Last year, Menendez was found guilty on all 16 counts, including extortion, obstruction of justice, acting as a foreign agent for Egypt, bribery, and conspiracy. He had accepted hundreds of thousands of dollars’ worth of bribes from three once-prominent New Jersey businessmen —  Wael Hana, Fred Daibes, and Jose Uribe.
