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

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.

The interim U.S. Attorney for Washington, D.C., demoted multiple senior-level officials in his office Friday who had previously overseen some of the most high-profile Jan. 6 prosecutions, as well as criminal cases against allies of Trump, multiple sources familiar with the matter tell ABC News.

At least seven attorneys were informed by interim U.S. attorney Ed Martin of their demotions Friday morning to line positions dealing with matters like misdemeanor crimes and other lower-level issues, the sources said.

Among the attorneys impacted was John Crabb and Elizabeth Aloi, supervisory-level attorneys who led the criminal contempt of Congress prosecutions of Trump allies Steve Bannon and Peter Navarro.

Kathryn Rakoczy, one of the lead attorneys who prosecuted members of the Oath Keepers for seditious conspiracy for their roles in the Jan. 6 attack on the Capitol, was also informed of her demotion -- as was Jason McCullough, who served on the team that prosecuted members of the Proud Boys including leader Enrique Tarrio.

House Minority Leader Hakeem Jeffries called the contentious meeting in the Oval Office "appalling," claiming the fallout will embolden Vladimir Putin and Russian aggression.

"The United States must not reward Russian aggression and continue to appease Putin," Jeffries wrote in a statement.

"President Zelensky and the Ukrainian people have stood on the side of democracy, freedom and truth. Their success is in the national security interests of the United States. We should stand with Ukraine until victory is won," he added.
