Do you need a license to practice law?
Elizabeth Warren practiced law for years in Massachusetts without a license.
Yes you do need a license. It is a felony in many states to hold yourself out as a lawyer when you’re not.
Here is a screen shot from Zero Hedge at the link. He clearly claims to be a licensed attorney, which is a crime:

That’s why he took down the website. It’s a crime for each client he represented. So he’s likely guilty of dozens of misdemeanors.
Depending on what states he ran his fraud scheme (if, in fact, he’s not licensed it’s fraud), if he traveled within the D.C. area it’s likely in one of those jurisdictions he committed a felony by claiming to be a lawyer.
