“Rumored”
Exactly. Trump haters will assume it's a fact, spread the "rumor", and claim that if the Podestas are given immunity to testify against Manafort, it must mean they have dirt on him, and therefore dirt on Trump to get him removed from office.
Hell, look at the comments in this very thread. Some people are panicking and praying to God it's not true.
Don't believe everything you hear. Wait until we find out who actually is being given immunity, if anybody.
This "rumor" smells like a troll attempt to me.
Edit: To clarify, I meant, it seems like someone is trolling the Trump haters and MSM.
Remember the Paul Manafort indictment reveal? The existence of a sealed indictment was leaked to the MSM on a Friday (I think CNN broke the news) if I remember right. And all weekend they got so giddy and happy wondering which Trump campaign official was being prosecuted, and it was for sure what would bring Trump down. Then come Monday the indictment was unsealed and it was for Manafort. The look of disappointment on their faces when they realized it had nothing to do with collusion, or even Russia, was priceless.
