It’s John Bolton vs Rudy Giuliani in a drag-down fight.

Bolton hit first, calling Giuliani a ‘hand grenade who’s going to blow everyone up’ in Trump’s Ukraine plan to get dirt on a political rival.

Now OG. is firing back, saying the former national security chief was ‘atomic bomb.’

Now it’s revealed that Bolton asked White House Russia adviser Fiona Hill to let the lawyers in on what was going on behind the scenes, warning ‘I am not part of whatever drug deal ‘ they’re cooking up.

Fittingly, the New York Times reported last week that Giuliani was himself under federal investigation for his dealings with Russia.

Is anyone surprised — given the President — that this is playing out like a bad TV reality show?
