Newsom hit with lawsuit threat as whistleblower begs Trump for help with 'monumental' fraud scandal

"What does the Stop Nick Shirley Act do? It basically makes it illegal for a citizen journalist to document fraud of taxpayer money and post that on the internet in the form of an internet video," he said.

Newsom signed the bill into law last week, and it is set to take effect Oct. 1. DeMaio told Fox News Digital that he and a "coalition of civil liberty protectors" are prepared to file a lawsuit challenging the law.

"We have a plaintiff and are putting together the legal briefs," he said, adding, "It is a matter of time before we're going to get before a judge to stop this act."

DeMaio said the planned lawsuit follows discussions with the Justice Department's Office for Civil Rights.

"I have asked the U.S. Department of Justice Office of Civil Rights to look at the Stop Nick Shirley Act … to see if they can do anything to intervene to prevent the implementation of this law. We have been dialoguing with the Department of Justice, and now we have a game plan as to how we will proceed forward in the courts to overturn this unconstitutional law," he said.

Addressing Newsom directly, DeMaio said, "Gavin Newsom, once again, you're a bully trying to silence citizen watchdogs into not exercising their First Amendment rights and exposing your fraud, the billions of dollars that you've allowed to be wasted of precious taxpayer funds, all because you want the benefit of these left-wing NGOs to help you politically."

DeMaio said Newsom and California's Democratic supermajority "created such a monumental problem with fraud of taxpayer money being abused that it's clear that it is intentional."

"You're going to be exposed as a bully," he told Newsom. "You're going to be exposed as the fraud ringleader."

In response, Newsom spokesperson Diana Crofts-Pelayo told Fox News Digital that "this law has nothing to do with Nick Shirley" and that "the real controversy here is that MAGA Republicans are either lying to create up fake conspiracy theories, or none of them know how to read."

Crofts-Pelayo said the law does not affect Shirley's journalism, which Newsom's office previously referred to as "grifting" and "lying," and does not hide fraud.

Fox News Digital reached out to the offices of California Assembly Speaker Robert Rivas and Senate President pro Tempore Monique Limón, both Democrats, for comment.
