I hope Manafort challenges the jurisdiction of the special counsel. Mueller was mandated to investigate "coordination and/or links... with Russia and individuals associated with the Trump campaign." Mueller has authority to pursue other crimes that may come to light in this investigation (such as Papadopolous lying to investigators) but I don't think that should include EVERY crime that Mueller can dig up on anybody in DC. 

If Mueller charges Tony Podesta for doing just what Manafort did, he will have left his Trump/Russia collusion mission so far behind that he will make Ken Starr look good. But if Mueller DOESN'T charge Tony Podesta for doing just what Manafort did, he will make any claim to be simply enforcing the law seem absurd. The only way to limit these potentially absurd results is to construe Mueller's mandate as "investigating coordination between Russia and individuals associated with the Trump campaign WHILE they were associated with the Trump campaign."
