The chairman of the US Joint Chiefs of Staff, Gen. Dan Caine, told senators on Thursday (April 30) that Vladimir Putin’s Russia has been assisting Iran during the ongoing conflict with the United States, raising fresh concerns about Moscow’s involvement in the widening regional war.
Speaking during a hearing before the Senate Armed Services Committee, Caine acknowledged Russian support for Tehran but declined to publicly disclose operational details.
“There’s definitely some action there,” the general told the lawmakers.
Caine cited the public nature of the hearing as the reason for withholding further specifics.
Roger Wicker accuses Russia of undermining US goals
The committee’s Republican chairman, Roger Wicker, backed Caine’s assessment and issued an even stronger warning about Moscow’s intentions.
“There’s no question that Vladimir Putin’s Russia is taking serious action to undermine our efforts for success in Iran,” Wicker said during the hearing.
The remarks marked one of the clearest public acknowledgements yet by senior US officials that Russia may be playing an active role in supporting Tehran as the conflict intensifies.
Growing fears of wider international involvement
The comments come amid escalating geopolitical tensions surrounding the Iran war, which has increasingly drawn in global powers.
US officials have repeatedly accused Russia and Iran of deepening military cooperation in recent years, particularly through weapons transfers, and intelligence coordination.
Senate hearing focused on Iran war and defense policy
The hearing took place as lawmakers questioned Defense Secretary Pete Hegseth and military leaders over the costs, strategy, and consequences of the Iran war, which began nearly two months ago.
The administration has defended the military campaign as necessary to prevent Iran from advancing its nuclear ambitions, while critics argue the conflict risks destabilizing the wider Middle East and stretching US military resources.
Lawmakers from both parties also discussed rising defense expenditures, threats to US troop deployments, and growing tensions involving NATO allies and Russia.
