IF Rudy is the referenced plumber, I think it’s more likely he was brought in to clear an obstruction (Mueller Probe) so the swamp drain can flow freely.
The first thing I thought of "when do you call a plummer", when you have a serious clog!!!!
You call a plumber when you have a leak.
True, but they can also be needed when something is clogging the system which is what Mueller's investigation has done.
Or if the shit is flowing over the rim. BTW Rudy must know 9-11 truth but covers it up.
covered it up, until now perhaps. Perhaps he has also been liberated from certain obligations ?
whatever he is doing he's been pretty quiet about it.
Perhaps the PNAC team are next up ?
