A double jeopardy case set to be argued at the Supreme Court on Thursday has led to speculation about the impact a ruling could have on prosecutions stemming from special counsel Robert Mueller’s Russia investigation, including that of former Trump campaign chairman Paul Manafort.

But while some believe the outcome of the case could potentially prevent states from prosecuting Manafort under their own laws should he receive a pardon from President Trump, some legal experts say the sheer volume of state charges available makes it unlikely Manafort will walk free.
