Two Democratic lawmakers have called on the U.S. Treasury Department to reverse a waiver that permits India to buy Russian oil, according to recent reports.

The lawmakers argue that the current arrangement provides what they describe as "material benefit to the enemy," referencing reports of Moscow providing assistance to Iran. The specific details of the Treasury waiver and its terms were not immediately detailed in available reporting.

The demand comes as energy prices have experienced increases, though the exact relationship between the waiver and current pricing trends remains unclear from available information. India has been one of the largest purchasers of Russian energy exports since international sanctions were imposed following Russia's invasion of Ukraine.

The Treasury Department has not immediately responded to the lawmakers' request. The waiver system has been part of the complex web of sanctions and exemptions implemented by the U.S. government to balance pressure on Russia while managing global energy markets.

The timing of the lawmakers' demand appears linked to broader concerns about Russia's international relationships and activities, particularly regarding Iran, though specific details about recent developments between Moscow and Tehran were not provided in the available reporting.
