Trump admin live updates: Trump calls Tesla dealership vandals terrorists

White House press secretary Karoline Leavitt read aloud a statement from Secretary of State Marco Rubio and national security adviser Michael Waltz on Trump's phone call with Ukrainian President Volodymyr Zelenskyy.

The two officials described the conversation between the two leaders as "fantastic" and that Trump "fully briefed" Zelenskyy on his call on Tuesday with Russia's Vladimir Putin.

"The two leaders also agreed on a partial ceasefire against energy," according to the statement shared from the podium. "Technical teams will meet in Saudi Arabia in the coming days to discuss broadening the ceasefire to the Black Sea."

Zelenskyy, in his own statement following the call, said he "supported" ending strikes on energy infrastructure and that "Ukraine confirmed that we are ready to implement it."

"We instructed our teams to resolve technical issues related to implementing and expanding the partial ceasefire," Zelenskyy said. "Ukrainian and American teams are ready to meet in Saudi Arabia in the coming days to continue coordinating steps toward peace."

White House press secretary Karoline Leavitt on Wednesday continued the administration's heavy criticism of the federal judiciary, even after Chief Justice John Roberts rebuked Republican calls to impeach judges.

"Americans can absolutely expect to see the continuation of the mass deportation campaign that has been successfully led by this president," Leavitt said from the briefing podium when asked about the legal battle over deportation flights to El Salvador.

"The judges in this country are acting erroneously," she said. "We have judges who are acting as partisan activists from the bench. They are trying to dictate policy from the president of the United States. They are trying to clearly slow-walk this administration's agenda, and it's unacceptable."

Leavitt added, "And not only are they usurping the will of the president and the chief executive of our country, but they are undermining the will of the American public -- tens of millions of Americans who duly elected this president to implement the policies that are coming out of this White House."

The attacks on judges from the Trump administration and their defiance of a court order over the weekend to turn around deportation planes have sparked concerns of a possible constitutional crisis.

Ukrainian President Volodymyr Zelenskyy's call with President Donald Trump was "good" and "very productive," a source in the Office of the Ukrainian President told ABC News.

Zelenskyy also agreed to set up a new meeting for the Ukrainian and U.S. delegations as soon as possible. Both sides will start working on this now, the source said.

President Donald Trump provided a small readout with his nearly one-hour call with Ukrainian President Volodymyr Zelenskyy, where he said they focused on his conversation with Russian President Vladimir Putin.

"Much of the discussion was based on the call made yesterday with President Putin in order to align both Russia and Ukraine in terms of their requests and needs," Trump wrote in a Truth Social post.

The president indicated that Secretary of State Marco Rubio and National Security Advisor Michael Waltz will have more information shortly.
