Tonight, on All In: A Supreme Court Justice and a United States Senator – corruption in the system as American’s confidence in it declines. Tonight, the stunning details from the indictment of Senator Robert Menendez. And the ProPublica reporting on Clarence Thomas & a new group of right-wing billionaires. Plus, President Biden's bold move to support the striking autoworkers, in person – and one day before Trump's own debate-dodge stunt. And the sad decline of Ron DeSantis, as Republicans say “no thanks” to “diet Trump.”

Guests: Jonathan Dienst, Nick Akerman, Michelle Goldberg, Justin Elliot, Rep. Katie Porter, Tara Setmayer, Jennifer Horn
