Top Trump ally New Gingrich and author of 'Understanding Trump,' warns that if false and/or compromising information continues to leak out of former FBI Director Mueller's investigation into Russian interference in 2016, the deputy attorney general might have to appoint a special counsel to investigate the current special counsel's investigation.
GINGRICH: I think he's furious. I think Trump sits there and says, let me get this straight, I know I didn't do anything with the Russians. Comey has said three times I didn't do anything with the Russians. Nobody on Capitol Hill has any proof I did anything with the Russians. And now I get an independent counsel who is going to mess up at least the next year, at a minimum, and who, by the way, you'll notice is expanding his charge.
I mean, now they're talking about not the Russians, they're talking about obstruction. Now they're talking about going and looking at financial files, if you believe the leak. And I said yesterday, you get two more leaks like this, Rosenstein is going to have to appoint a special counsel to investigate the special counsel.
