I think Lanny Davis has 3 main goals here, although a 4th goal may be conceivable:
1) Get on TV and insult Trump as often as possible.
2) Get access to information which can be funneled to the Clinton Foundation for future benefit.
3) Squeeze money out of a GoFundMe site
4) Help Cohen if it’s not too much trouble.
No doubts but Lanny Davis is one of the smoothest crooked lawyers you will ever see. He is a Clinton insider from the word go.
