U.S. federal prosecutors have opened preliminary criminal investigations into Colombian President Gustavo Petro over alleged links to drug traffickers and possible illicit financing of his 2022 campaign, according to a report by The New York Times.
The previously undisclosed probes are being conducted by federal prosecutors in Manhattan and Brooklyn and involve specialists in international narcotics trafficking, as well as agents from the Drug Enforcement Administration and Homeland Security Investigations, the newspaper said, citing people familiar with the matter.
Investigators are examining, among other issues, whether Petro held meetings with individuals connected to drug trafficking networks and whether his presidential campaign solicited or received donations from such actors. The two investigations are being carried out independently and remain in their early stages, with no certainty that they will lead to formal criminal charges.
There is no indication that the White House played any role in launching the investigations, according to the report. However, the inquiries emerge in a broader context of heightened tensions and fluctuating diplomacy between Bogotá and Washington.
Relations between Petro and U.S. President Donald Trump have been volatile, marked by sharp public exchanges, threats of tariffs that were never implemented, and the temporary revocation of Petro’s U.S. visa. Trump has repeatedly accused Petro of failing to curb narcotics production and has described him in highly critical terms, while Petro has denounced what he characterises as political pressure and interference.
The U.S. Treasury Department last year imposed sanctions on Petro, members of his family and senior officials, including Interior Minister Armando Benedetti, alleging links to narcotics activity. The measures, which included asset freezes and travel restrictions, were justified by Washington on the grounds that cocaine production in Colombia had reached record levels and that the government had offered concessions to armed groups involved in trafficking.
Petro has rejected those claims, insisting that his administration has strengthened seizures of cocaine and slowed the rate of expansion of coca cultivation. He has also denied any knowledge of illicit funds entering his campaign, dismissing the allegations as politically motivated attacks.
Colombia’s Attorney General is examining charges that Petro’s son – Nicolás Petro – received money from individuals linked to illicit activities during the 2022 campaign. While his son acknowledged receiving funds that were not reported, no criminal charges have been filed against the president himself, and Petro has maintained he was unaware of the campaign “donations”.
According to the NYT, the U.S. investigations are taking place amid a broader strategy in which Washington has increasingly used legal and judicial tools to advance foreign policy objectives. Analysts say such actions could serve as leverage in bilateral relations or influence political dynamics in allied countries.
The timing of the probes is particularly sensitive, as Colombia prepares for presidential elections on May 31, with a potential runoff in June. Petro, the country’s first leftist president, is constitutionally barred from seeking re-election but has actively backed his political successor with hardleftist Iván Cepeda.
The allegations could reverberate through the electoral campaign, where relations with the United States remain a central issue. Candidates on the right have emphasised the importance of maintaining close ties with Washington, while figures on the left have framed U.S. actions as a challenge to Colombia’s sovereignty.
Despite months of tensions, diplomatic relations between the two countries have shown signs of stabilisation in recent weeks. Petro and Trump held a bilateral meeting at the White House earlier this year, which both sides described as constructive, and officials have since sought to rebuild communication channels.
Even so, uncertainty persists over the trajectory of the relationship, particularly as Washington continues to prioritise counternarcotics cooperation with Colombia, historically one of its closest partners in the region.
Petro has consistently denied any links to drug trafficking and has pointed to his government’s security strategy, which includes negotiations with armed groups and efforts to reduce violence, as evidence of a broader approach to the drug trade.
The start of U.S. investigations add a new layer of complexity to an already fraught political and diplomatic landscape, with potential implications not only for Petro’s post-presidential future but for Colombia’s ties with its most important security ally.
