President Donald Trump spoke with both Russian President Vladimir Putin and Ukrainian President Volodymyr Zelensky on July 4, according to Moscow and Kyiv. The White House has not confirmed the conversations, nor have they disputed that they occurred. 

The Russian foreign ministry described the call, their fourth this year, as “businesslike and highly constructive,” according to CNN. They added that Trump had “reaffirmed his readiness to facilitate the earliest possible cessation of hostilities” between Russia and Ukraine.

“The Russian side once again emphasized the preference for a political and diplomatic resolution to the conflict,” according to the foreign ministry, which said that “Kyiv and its European sponsors are banking on prolonging and even escalating the conflict.”

“Our president has outlined the reality of the situation on the battlefield, where the Russian Armed Forces are advancing confidently,” the ministry said.

Zelensky said he had a “very good call” with Trump on Saturday. “There is a real prospect to put an end to this war, and America’s resolve is decisive,” Zelensky said.

The calls came in advance of a NATO summit set to begin in Ankara, Turkey, starting Tuesday, which President Trump plans to attend.
