A bipartisan group of senators wrote to Secretary of State Marco Rubio on Wednesday urging him to “surge resources to quickly enable critical internet freedom support” to protesters in Iran, pointing to funding cuts that have stretched resources for such programs.

“Today, many of the NGOs and technology providers that maintain these tools are facing closure due to funding cuts and more importantly, fewer Iranian citizens can share their videos and messages with the world and each other,” the letter warns. “Without the continuous operation of internet freedom programming carried out by the State Department and Open Technology Fund, millions of Iranians will lose their last secure window and voice to the outside world.”

The lawmakers, Sens. James Lankford (R-OK), Jacky Rosen (D-NV), Lindsey Graham (R-SC) and Cory Booker (D-NJ), warned that if U.S. programs fully lapse, regime-controlled programs and state media will step into the gap, “giving the regime near-total control over the digital space and putting users at far greater risk.”

“As we watch brave Iranians take to the streets, it is clear that supporting the Iranian people’s access to information is not a partisan issue but a matter of national security, as well as meeting legislative requirements for a strategy for promoting internet freedom in Iran,” the lawmakers said, pointing to existing legislation mandating the State Department to expand internet access in Iran. “The United States must pair its maximum pressure on the regime with maximum support for the Iranian people.”

The letter comes at a time when Congress has offered few of its own strategies to respond to the wave of protests around Iran — which, according to Rubio, have now largely been put down by the regime.

Such efforts to promote free internet access to the Iranian people, amid efforts by the regime to impose an internet blackout, have emerged as a key area of bipartisan agreement.

Much of the U.S.’ global communications programming, including funding for promoting internet access, was slashed last year amid cutbacks to various foreign aid programs. Some prominent Republicans have criticized the administration, saying that government-sponsored news programming and communications assistance have failed to meet the moment in Iran.

The letter emphasizes the “long-standing and bipartisan commitment” to supporting internet freedom programs, which are “more important than ever as the people of Iran protest against the regime in record numbers.” The legislators noted that prior administrations have, for two decades, supported various anti-censorship and internet freedom tools in Iran, and that Congress passed legislation in 2024 supporting such programs.

“Without U.S. leadership, an entire generation of Iranians would have remained in the dark — and the most powerful source of pressure against the Islamic Republic, the Iranian people themselves, would have been neutralized,” the letter reads.

It notes that the existing U.S. programs allowing a small number of Iranians to remain online had “proved decisive” during the Israel-Iran war last summer to demonstrate the division between the Iranian people and the regime, and said that expanded internet access now “would put a spotlight on the increasingly securitized atmosphere that is cracking down on dissent.”
