Federal government just four days away from potential shutdown

Senator Bob Menendez is back on Capitol Hill where he faces questions about criminal charges and a growing list of his Democratic colleagues calling on him to resign. Menendez tells NBC News' Ryan Nobles he won't step down because he is innocent. Meanwhile, the federal government is just four days away from a potential shutdown. (Correction: An earlier version of this description said Sen. Menendez was not taking questions. This has been updated.)
