Sen. Lindsey Graham’s Influence on U.S.-Iran Relations
Senator Lindsey Graham from South Carolina has been a prominent advocate on Capitol Hill for President Donald Trump’s actions against Iran. However, his unwavering support for the now-dismantled U.S. Agency for International Development (USAID) has raised questions about the real impact of these military actions, possibly providing advantages for both Trump and the Republican Party.
Even as concerns about USAID’s financial management grew, Mr. Graham continued to champion the agency. This was despite clear indications that taxpayer money was misused, funneled into organizations like al-Qaeda.
In 2025, Trump effectively put an end to USAID, and many Republican senators, including Graham, admitted that the agency could benefit from reform. Still, prior to Trump’s decisive cuts, a significant amount of taxpayer money intended for USAID ended up supporting terrorist organizations, notably Hamas, which plays a critical role in ongoing unrest in the Middle East. This financial backing was a point of contention, especially as it was used to rationalize military action against Iran.
Hamas, having received substantial funding from the U.S., now stands as a formidable opponent to U.S. interests in Iran, potentially lengthening the conflict. They have reached out to Iran, urging the nation to “activate all fronts” against the U.S.-led endeavors.
The Iranian regime faces threats from Hamas, leading to significant geopolitical tensions affecting oil prices and the broader global economy, potentially jeopardizing the Republican Party’s midterm electoral prospects and Trump’s legacy.
This could result in a prolonged conflict that exposes the limitations of American intelligence efforts abroad, or perhaps it reveals something even more concerning.
Lindsey Graham’s involvement in these developments is unmistakable.
In early 2025, Graham’s previous backing of USAID came to light when a few moderate senators resisted Trump’s calls for drastic changes to the agency. Graham praised USAID’s work, asserting that it was making a positive impact globally and improved U.S. foreign and national security policy.
Inevitably, questions arose about how Graham could reconcile supporting an agency that allegedly funded terrorist entities while advocating for U.S. goals in the region.
Despite troubling warnings about USAID, Graham’s enthusiasm for continued financial support remained evident, while the Senate largely neglected its oversight responsibilities, leaving the House to take charge. Concerns were raised that USAID and the State Department directly assisted Hamas and similar organizations.
From 2007 to 2024, allegations emerged that USAID and the State Department provided at least $122 million to NGOs tied to designated terrorist groups, some of which openly promoted violence. Yet, Graham, when approached for his insights into oversight efforts, did not respond.
Moreover, it’s believed that assistance from international organizations could have directly contributed to Hamas’s violent actions in the region. For example, just days before a significant attack in October 2023, USAID granted funds to an NGO closely associated with Hamas, which had collaborated on various initiatives.
Graham’s longstanding role as a staunch advocate for USAID has been apparent as taxpayer resources were directed towards groups linked to terrorism.
With Trump’s presidency facing new threats, Graham’s influence as an unofficial advisor raises questions about the guidance available to the president on national security matters. Despite apparent philosophical divides, Graham has maintained a close rapport with Trump, even benefiting in the 2020 primaries from voters preferring a candidate aligned with America First ideologies.
However, as the Iran situation continues to deteriorate, some Republicans have begun to question Graham’s role as a national security figurehead. Additionally, there are concerns regarding the overall direction of Trump’s legislative agenda, notably during discussions surrounding the SAVE America Act.
Many conservatives are convinced that Graham remains committed, perhaps a bit hesitantly, to the filibuster, which is a point of contention among his peers.
As the neoconservative faction within the party turns its sights to the 2028 presidential race, they are keen to regain influence reminiscent of the Bush era, presenting a contrasting viewpoint to Trump’s coalition-building efforts.
With significant foreign policy challenges and the party’s trajectory in question, Graham has continued to assert the importance of U.S. interventionism, much to the dismay of voters who had hoped for a shift towards an America First agenda. This tension could hinder Trump’s policies and undermine the coalition he built, possibly allowing neoconservatives to reclaim a foothold in the Republican Party.
In his recent assertions, Graham has escalated discussions regarding U.S. involvement in the Iran conflict, openly questioning Saudi Arabia’s commitment to mutual defense alignment with the U.S. His insistence suggests a deepening entrenchment in the conflict.
Despite challenged policies at USAID and GOP tensions, Graham’s rhetoric indicates he may continue advocating for an active American presence on the global stage, although it remains to be seen how this aligns with the evolving priorities of Republican voters.
