Trump 2nd term updates: Trump excludes low-value shipments from looming tariffs

The union representing NOAA and National Weather Service staffers told ABC News that they've been informed of 586 probationary employees terminated from NOAA Thursday, with 108 of those cuts coming from the National Weather Service.

"We understand that an additional 800 NOAA probationary employees may be terminated this afternoon," National Weather Service Employees Organization General Counsel Richard Hirn told ABC News in an emailed statement.

NOAA declined to confirm the number of staffers affected by the cuts in a statement to ABC News earlier today, saying they "don't discuss personnel matters."

Pennsylvania Republican Rep. Brian Fitzpatrick, a Ukraine ally on Capitol Hill, said in a statement that "it was heartbreaking" to witness the "events that transpired in today's meeting" at the White House.

"This can and will be fixed. A strong, sovereign Ukraine is essential for global stability in the face of Putin's ongoing aggression. Lasting peace can only be achieved through unwavering strength," he said.

GOP Reps. Don Bacon of Nebraska and Rep. Mike Lawler of New York were also critical in separate posts on X regarding what transpired today at the White House and if Ukraine's future is impacted.

"Diplomacy is tough and often times there are serious differences of opinion and heated exchanges behind closed doors. Having this spill out into public view was a disaster — especially for Ukraine," Lawler said.

A member of the Ukrainian delegation who attended the talks at the White House confirmed to ABC News that after a fiery verbal exchange between Zelenskyy and Trump, the Ukrainian side waited in a separate room, and was ready to continue negotiations.

However, White House staff told them the meetings were canceled and they told the Ukrainians "to leave," according to the official.

"We were prepared for a productive meeting, but they clearly wanted to start a fight," the source told ABC News.

When asked if the source believed Zelenskyy was deliberately provoked, the source replied, "I think so."

Zelenskyy was slated to give remarks and participate in a "fireside chat" at the conservative Hudson Institute think tank in Washington, D.C., on Friday afternoon, but the event has been canceled.

Zelenskyy was going to "discuss U.S.-Ukrainian relations, the state of the war, and the path forward for Ukraine," according to the institute.
