The legal action is in response to recent statements the Senator made on the social media platform X regarding CZ’s recent pardon from U.S. President Donald Trump. CZ’s legal team has demanded a public retraction, calling the Senator’s claims false and misleading. 

Senator Elizabeth Warren Accuses CZ of Money Laundering, Faces Backlash 

The conflict began on October 23, when U.S. President Donald Trump issued a full pardon to Changpeng Zhao. This pardon eased CZ’s 2023 conviction, which was for failing to maintain an effective anti-money laundering program at Binance. This was a violation of the Bank Secrecy Act.

For this compliance failure, CZ had served a four-month prison sentence and paid a personal fine of $50 million. His company, Binance, also paid a massive $4.3 billion settlement to authorities. After this, he also decided to step down from his CEO position. 

It is important to note that this legal case did not involve charges of fraud, and no victims were identified for the same. 

CZ pleaded guilty to a criminal money laundering charge and was sentenced to prison.

But then he financed President Trump’s stablecoin and lobbied for a pardon.

Today, he got it.

Minutes after the White House announced the pardon, Senator Elizabeth Warren shared a post on X. In the post, she stated that CZ had pleaded guilty to a criminal money laundering charge and was sentenced to prison. She directly linked the pardon to CZ having financed President Donald Trump’s stablecoin, suggesting a corrupt exchange. 

However, community notes attached to the post on X and subsequent reporting clarified that CZ was never charged with money laundering itself. His plea was specifically failure of the anti-money laundering program.

CZ Plans to Drag Senator Warren into Court

Over serious allegations, CZ responded to Senator Warren’s post quickly. He directly challenged her to get her facts straight, emphasizing a critical legal distinction. He pointed out that he was convicted for a compliance program failure, not for the act of money laundering. His statements show that the case involved no fraud and no prior criminal history. The clarity of this distinction became a central point of this entire dispute. 

Following this word battle, CZ’s legal team moved forward with a formal challenge. On October 28, his attorney, Teresa Goody Guillen, sent a demand letter to Senator Warren. The letter allowed the Senator to retract her statements or face an imminent defamation lawsuit. 

“Mr. Zhao will not remain silent while a United States Senator seemingly misuses the office to repeatedly publish defamatory statements that impugn his reputation,” Goody Guillen stated in a draft letter. “Accordingly, Mr. Zhao respectfully immediately requests the retraction of these false statements, both within the resolution and on X… Mr. Zhao reserves his right to pursue all legal remedies available to address these false statements.”

Senator Warren vs. Crypto Industry 

This legal confrontation is not an isolated incident but part of a much larger political war over the future of cryptocurrency in the United States. 

Senator Warren, a ranking member of the Senate Banking Committee, has been a long-time and vocal critic of the digital asset industry. Since 2021, she has demanded the formation of strict regulations. Following the collapse of the FTX exchange, she co-sponsored the Digital Asset Anti-Money Laundering Act, aiming to impose stricter rules on the industry to prevent its use by terrorists and other bad actors. She has also been critical of business ventures linked to the Trump family, which she connects to the crypto industry.
