Argentine lawmakers have moved to challenge the federal prosecutor leading the criminal investigation into the $LIBRA cryptocurrency scandal, accusing him of delays and obstruction that they say have undermined congressional oversight of the case.
The push centers on Eduardo Taiano, the federal prosecutor who has led the $LIBRA probe since its early stages. Members of Argentina's Chamber of Deputies formed a special investigative commission to examine the scandal, and their public criticism of Taiano marks one of the sharpest clashes between the legislative and judicial branches over the handling of a crypto-related case in Latin America.
Why Argentine lawmakers want the lead prosecutor removed
On November 4, 2025, Argentina's Chamber of Deputies commission on $LIBRA held a session in which deputy Monica Frade proposed a formal complaint against prosecutor Taiano and judge Marcelo Martinez de Giorgi. The lawmakers alleged that both officials had delayed proceedings and obstructed the commission's work, according to an official statement from Argentina's lower house.
Bloc leader German Martinez echoed the accusations, stating that Taiano and the judge had hindered the commission's ability to gather evidence and testimony. The complaints reflect frustration that had been building for months as the legislative body struggled to access case materials held by the judiciary.
Taiano had been actively pursuing the criminal case. In August 2025, he secured a court order from judge Maria Servini to freeze more than $323,275 in USDT tied to the $LIBRA investigation, demonstrating that the prosecutorial track was producing concrete enforcement actions even as lawmakers questioned his pace.
The executive branch had also created a separate investigative task force through Decree 114/2025 in February 2025, tasked with collecting information for prosecutors and courts. The parallel tracks, executive, legislative, and judicial, set the stage for the institutional friction that eventually erupted publicly.
What the leadership challenge could mean for the Libra investigation
The commission's push to sanction Taiano did not result in his removal from the case. When the commission wrapped up its work on November 18, 2025, the opposition report fell one signature short of the 15 needed to be elevated to the full chamber for a vote. The report secured only 14 signatures.
That procedural shortfall is significant. It means the formal complaint against Taiano never advanced through the full legislative process, leaving the prosecutor in place on the criminal case. A separate court decision in December 2025 also rejected a request to remove Taiano, reinforcing his position.
Any disruption to prosecutorial leadership in a case of this complexity could slow momentum. Replacing a lead prosecutor mid-investigation typically forces a new official to review months of evidence, re-establish relationships with witnesses, and rebuild legal strategy. For Argentina's crypto community, which has watched institutional interest in digital assets grow globally, a stalled probe risks eroding confidence in local enforcement.
The distinction between political pressure and formal investigative outcomes matters here. Lawmakers publicly accused the prosecutor, but the judicial system retained him. The investigation continues under its original leadership.
Why the prosecutor dispute matters for Argentina's crypto policy debate
The $LIBRA affair has become a test case for how Argentina handles high-profile crypto scandals across its institutions. With the executive branch running its own task force, Congress operating a special commission, and the judiciary conducting a criminal investigation, the case has exposed coordination gaps and competing interests at every level of government.
The commission's inability to compel cooperation from the judiciary highlights a structural challenge. Legislative oversight bodies in Argentina lack the authority to directly remove prosecutors or judges from cases. Their tools are limited to public pressure, formal complaints, and political signaling.
For a country where tokenized financial products and crypto adoption have attracted growing attention, the credibility of enforcement mechanisms matters. If prosecutors are seen as either too slow or politically shielded, public trust in the regulatory framework weakens. If lawmakers are seen as interfering in judicial proceedings for political gain, the same trust erodes from a different direction.
The $LIBRA case also has an international dimension. U.S.-based legal proceedings have run in parallel, with attorney Max Burwick noting that court orders in related litigation represent "an important step toward protecting our client, the proposed class, and the legitimacy of the crypto industry."
The Argentine probe continues under Taiano's leadership. Whether the political pressure from Congress produces longer-term consequences for the prosecutor's tenure or the investigation's direction will depend on developments in both the legislative and judicial arenas in the months ahead.
