White House adviser urges Ukraine to tone down criticism

WASHINGTON (Reuters) - The White House continued to press Kyiv on Thursday with its efforts to bring an end to the Russia-Ukraine conflict, urging it to rein in criticism and quickly sign a minerals deal pushed by U.S. President Donald Trump.

"They need to tone it down and take a hard look and sign that deal," Mike Waltz, the White House national security adviser, said in an interview with Fox News.

Pushback from Ukraine on the minerals deal and how Trump is carrying out peace talks is simply unacceptable, Waltz said, given everything the United States has done for Ukraine.

Waltz's comments come a day after Trump and Ukrainian President Volodymyr Zelenskiy traded insults, with Trump calling Zelenskiy a dictator and Zelenskiy saying the U.S. president was living in a disinformation bubble and spewing talking points from Moscow.

However, Waltz said U.S. differences with Ukraine were not irreconcilable, saying: "The president also said how much he loves the Ukrainian people."

Ukraine and European leaders have balked at being left out of peace talks begun after Trump and Russian President Vladimir Putin spoke by telephone last week.

Waltz denied that U.S. allies and Ukraine were not being consulted.

"There's a term for this in diplomacy. It's called shuttle diplomacy, because bringing everybody to the table at once just hasn't worked in the past," he said.

"So we've engaged one side, we've engaged the other side, and then we're going to have a process moving forward under President Trump's direction and leadership."
