A coalition of lawmakers from both parties is urging the Trump administration to reverse course and impose new sanctions on Milorad Dodik, the former president of Bosnia's Republika Srpska entity. In a letter to Treasury and State Department officials, the legislators argue Dodik's continued efforts to undermine the Dayton Peace Accords and advocate for secession demand a forceful U.S. response, just months after President Trump lifted previous penalties.
Legal Mandate and Bipartisan Pressure
The letter, led by Senator Jeanne Shaheen (D-N.H.) and Senator Thom Tillis (R-N.C.), contends that federal law requires sanctions against individuals threatening stability in the Western Balkans. They specifically cite provisions in the 2026 National Defense Authorization Act (NDAA), which mandated action by March 18 of this year. The lawmakers state that Dodik's conduct meets the legal criteria, creating an obligation for the administration to act.
"The law, which outlines specific criteria, requires the imposition of sanctions no later than 90 days following enactment," the bipartisan group wrote. They detailed multiple instances where Dodik has openly challenged the post-war constitutional order in Bosnia and Herzegovina.
From Sanctions to Rehabilitation and Back
Dodik's relationship with U.S. sanctions has fluctuated with administrations. The Biden administration sanctioned him in 2022 for corruption and threats to Bosnia's territorial integrity, with additional penalties for family members following in early 2025. President Trump revoked those sanctions in October 2025 without public explanation, a move some interpreted as an attempt to reset relations with Serb leaders who maintain ties to Russia.
The lawmakers acknowledged this diplomatic rationale but declared it moot. "While we recognize that the Trump Administration's decision... may have reflected an attempt to put Bosnia and Herzegovina on a path to greater political stability, Mr. Dodik's subsequent actions have made it clear that he has no interest in pursuing that path," they wrote.
A Pattern of Provocation
The letter catalogs what the signatories describe as a sustained campaign to dismantle the Bosnian state. They highlight Dodik's participation in January celebrations of "Republika Srpska Day," a holiday courts have ruled illegal due to discrimination against non-Serbs. They also note his ongoing influence over his former political party and the current Republika Srpska president, as well as efforts to hire a Washington lobbying firm explicitly to lobby for independence.
Further evidence includes "divisive rhetoric" against ethnic minorities and attempts to undermine the Office of the High Representative, the international body overseeing the Dayton Accords. The lawmakers cited a provocative incident where another recently delisted Bosnian official, Staasa Kosarac, sent a Nazi-era paramilitary helmet to the High Representative's office.
Broader Foreign Policy Context
This push comes as the Trump administration navigates multiple complex foreign policy challenges, from managing escalating tensions in the Middle East to deploying new tools for direct communication with its political base. The bipartisan pressure on Balkans policy underscores how regional stability issues continue to demand Washington's attention, even amid global crises.
Signatories and Strategic Weight
The letter carries significant weight due to its signatories. They include senior members of key committees: Senator Roger Wicker (R-Miss.), chairman of the Armed Services Committee; Senator Elizabeth Warren (D-Mass.), ranking member on Banking; and House members like Rep. Mike Turner (R-Ohio) of the Armed Services Committee and Rep. Ann Wagner (R-Mo.) of the Intelligence Committee. Senators Chuck Grassley (R-Iowa) and Dick Durbin (D-Ill.) also signed.
In their conclusion, the lawmakers framed the issue as a core U.S. national security interest. "The United States has played an important role in maintaining peace and stability in Bosnia and Herzegovina," they stated. "It is in our national security interest to ensure that actors who seek to undermine over thirty years of hard-fought peace are held to account before greater instability ensues." The administration has not yet issued a public response to the congressional demand.
