Michael John Avenatti (born February 16, 1971) is an American lawyer and businessman. Avenatti is best known for suing President Donald Trump on behalf of porn star Stormy Daniels in an attempt to prove that Trump paid Daniels to stay silent during their affair.

Avenatti said that he would run for president in 2020 if Trump runs for re-election and if no other candidate is good enough to beat Trump.
