The Justice Department and FBI have a new communist financier in their crosshairs for alleged financial crimes: James “Fergie” Cox Chambers Jr., the estranged bad-boy heir to the Cox cable empire.

On Friday, Spanish police detained Chambers on the luxury island of Ibiza, in response to an international arrest warrant, according to sources. Chambers is allegedly wanted for money laundering and providing support to Hamas, following years of financing anti-Israel and anti-West organizations and protests. The transnational network he helped fund and support is kicking in to cast him as a victim of the Trump administration’s “fascism,” while critics are cheering the arrest as long overdue.

A spokesman for Spain’s Balearic Islands police branch, which includes Ibiza in its jurisdiction, told Fox News Digital that a U.S. citizen was arrested on charges tied to an international arrest warrant Friday under an international arrest warrant seeking his extradition to the United States. The spokesman did not confirm the identity of the citizen, but sources told Fox News Digital that the individual is Chambers.

A convert to Islam, Chambers represents the fusion of socialist and communist activists with Islamist interests that seek the destruction of the West, free enterprise and the state of Israel and the rise of political Islam, communism and a new Palestinian state.

The arrest is a significant move by the Trump administration as it targets far-left financiers allegedly engaged in supporting political violence. In this case, as in other investigations, federal authorities are following the money and investigating potential tax and financial crimes.

FBI Co-Deputy Director Chris Raia recently told Fox News Digital that investigators at the FBI’s Joint Mission Center have identified subjects tied to financing violent protest activity and have been building prosecutable cases.

Chambers is now the estranged heir of Cox Enterprises, walking away from the family company in 2023 with a payout estimated at about $250 million after a falling out with his family over the company’s support for Atlanta’s controversial public safety training center, known by critics as “Cop City.” In April, a grand jury indicted three alleged Antifa-linked protesters accused of throwing firebombs at the general contractor of the Atlanta police training center.

Following the Oct. 7, 2023, Hamas terrorist attacks, Chambers became one of the most prominent financial backers of “Palestine Action,” later renamed “Unity of Fields,” while also funding legal defense efforts for activists involved in anti-Israel demonstrations and direct-action campaigns in the United Kingdom and the U.S.

He praised the Oct. 7 Hamas attacks as a “moment of hope and inspiration,” told Mother Jones that “the most important thing for the prosperity of humanity is the destruction of the US” and said, “I chant death to America every day.”

In early February 2024, Chambers was photographed in his newly adopted city of Tunis in the North African nation of Tunisia, framing his narrative as a pious Muslim convert, with a red-and-white Palestinian kefiyyeh scarf draped over his shoulders, a black Muslim prayer cap on his head and a small beard on his face, a tradition that follows the sunnah, or practice, of Muhammad, the prophet of Islam.
