Why did Rudy Ghoul-liani join Team trumpo?

Maybe he didn't hear about all the high power law firms that turned down
working for trumpo because he won't take their advice -- or he will
stiff them on their bill (as he has done before) -- or they know that
trumpo will ultimately and unceremoniously dump them.

I wonder how long it will take for The Ghoul to get thrown under the bus.
