Fresh off a win after his lawsuit helped lead to Jeff Epstein’s arrest for sex trafficking, author and political commentator Mike Cernovich has launched a GoFundMe campaign to wage a legal battle to unseal deals made in sexual harassment cases involving members of Congress.

Cernovich had lead the charge against Epstein, filing a lawsuit to unseal a large amount of files in the case that were previously withheld from the public. Epstein was arrested on Saturday for allegedly sex trafficking dozens of minors in New York and Florida between 2002 and 2005.
