WASHINGTON (AP) — Venezuelan opposition leader María Corina Machado said she presented her Nobel Peace Prize medal to President Donald Trump at the White House on Thursday even as he has questioned her credibility to take over her country after the U.S. ousted then-President Nicolás Maduro.

The Nobel Institute has said Machado could not give her prize to Trump, an honor that he has coveted. Even if it the gesture proves to be purely symbolic, it was extraordinary given that Trump has effectively sidelined Machado, who has long been the face of resistance in Venezuela. He has signaled his willingness to work with acting President Delcy Rodríguez, who had been Maduro’s second in command.

“I presented the president of the United States the medal, the Nobel Peace Prize,” Machado told reporters after leaving the White House and heading to Capitol Hill. She said she had done so “as a recognition for his unique commitment with our freedom.”
