Under Secretary of State for Political Affairs Victoria Nuland, known for her ardent support for Ukraine and hawkish anti-Russia views, will retire in the coming weeks.

Secretary of State Antony Blinken announced the news on Tuesday and lauded Nuland for putting “diplomacy back at the center of our foreign policy and revitalize America’s global leadership at a crucial time for our nation and the world.”

“What makes Toria truly exceptional is the fierce passion she brings to fighting for what she believes in most: freedom, democracy, human rights, and America’s enduring capacity to inspire and promote those values around the world,” Blinken said in a statement.

Nuland served in the State Department for more than 30 years, serving under six presidents and 10 secretaries of state.
