U.S. Ambassador to Ukraine Bridget Brink is stepping down, the State Department confirmed Thursday, as the Trump administration ramps up its efforts to broker a peace deal between Russia and Ukraine.

Tammy Bruce, a State Department spokesperson, said Brink would be leaving her role, though she didn’t give a specific departure date. 

The news comes at a critical moment for U.S. foreign policy as officials work to ease tensions and end the grinding war in Eastern Europe.

Brink, a career diplomat with decades of experience, was nominated by then-President Joe Biden and unanimously confirmed by the Senate in May 2022, just months after Russia launched its full-scale invasion of Ukraine. 

She became the first U.S. ambassador to serve in Kyiv since 2019, helping reestablish America’s diplomatic presence after embassy staff were evacuated in the early days of the war.

Before serving in Ukraine, Brink was the U.S. ambassador to Slovakia and worked in top roles at the National Security Council. She speaks Russian and is known for strongly defending U.S. interests in Eastern Europe.

While in Ukraine, Brink was a vocal supporter of American military aid and often appeared publicly with Ukrainian leaders. Her resignation comes as the Trump administration shifts focus toward ending the war through diplomacy and renewed talks with Russia.

Also on Thursday, U.S. and Russian officials held rare face-to-face talks in Istanbul aimed at repairing long-strained diplomatic relations. The State Department said the two sides exchanged formal notes to finalize an agreement that would stabilize banking services for each country’s embassies, a step seen as key to keeping diplomatic missions operational.

In recent years, both countries have imposed financial restrictions on each other’s embassies and slashed staffing due to the fallout from the war. A finalized banking deal could open the door to restoring some of those lost diplomatic connections.

The State Department said follow-up talks are expected, though no date has been set.

Brink’s departure lands at a moment of major transition in U.S. foreign policy. Her exit may also clear the way for a new ambassador more closely aligned with the Trump administration’s push for a ceasefire deal.

The State Department did not immediately respond to Fox News Digital’s request for comment.
