Real Faker! New ‘RHONJ’ Cast Member Jim Marchese Lied About Link To Giudice Prosecutor — U.S. Attorney’s Office Says, ‘We’ve Never Heard Of Him'

Jim Marchese is a reality TV newbie, but the new Real Housewives of New Jersey cast member is learning quickly when it comes to fudging the truth for the cameras. After Housewife Amber Marchese’s hubby bragged in a preview clip about his ties to the “attorney general that is prosecuting” Teresa and Joe Giudice, RadarOnline.com reached out to the attorneys’ office — only to find out that they’ve never heard of him.

Listen! 'RHOP' star Wendy Osefo breaks down the “most intense fight in the show's history” in under 2 minutes.

Marchese made the claims in a recently released promo clip for the show, where he is shown telling Teresa's brother, Joe Gorga in a menacing and threatening tone, "I work with the same f**king attorney general that is prosecuting your brother, you dumbf**k."

Now, the United States Attorneys' Office handling the Giudice bankruptcy and fraud case​ is speaking out exclusively to RadarOnline.com to slam Marchese’s claims.

"First of all, this man is incorrect,” a spokesperson for the United States Attorneys' Office told RadarOnline.com. "The Attorney General isn't prosecuting the Giduices. The United States Attorneys' Office is. "No one involved with the prosecution has any idea who that man is."

A source close to the cast told RadarOnline.com, "Jim continues to make these threats and ridiculous claims throughout several episodes of the show. He is trying to assert his authority and intimidate Joe and Teresa. In reality, he has no power or clout with anyone connected to the government's case against the Giudice's. He is full of hot air."

Marchese, no stranger to allegations of being on the wrong side of the law, previously found himself in the crosshairs of the United States Justice Department, when his stint as a whistleblower against his former employer, Cell Therapeutics landed him in hot water.

Marchese alleged that the company falsely marketed a a cancer drug and charged Medicare millions of dollars. According to the New York Times,the feds were so impressed with Marchese, they sued the company.
