Mike Waltz, the U.S. Ambassador to the United Nations, is urging broad reforms at the global body, with combating antisemitism at the forefront of the agenda as the Trump administration seeks sweeping institutional changes.

Waltz said that addressing antisemitism must be a cornerstone of any effort to overhaul the United Nations, coupled with a renewed focus on what he described as its founding mission of maintaining international peace and security.

"The U.N. has an atrocious history and record when it comes to antisemitism. Number one, it's a cesspool for antisemitism in many ways," Waltz said during an interview, according to Fox News. "This administration is determined to fight it."

He suggested that U.N. focus on Holocaust survivor testimony during its forums. 

"My recommendation to the U.N. is, get the diplomats and the politicians out of the way, let's just hear from the survivors because their stories are compelling, they are tragic, they need to be heard and documented, and they certainly can't ever be denied," Waltz said.
