People working closely with Ukrainian President Volodymyr Zelensky have been in contact with Trump administration officials over the past several weeks discussing the relationship between the two presidents, according to four people with knowledge of the talks. Based on those conversations, Ukrainian officials came to expect that Trump would make a statement of support before Zelensky met with Russian President Vladimir Putin in France for peace talks. A statement might even come via Twitter, they said they were told.

“Through all the signals we got, we firmly believed there would be a statement,” a senior Zelensky administration official told The Daily Beast.

But as Saturday and Sunday ticked by, there was only silence from the White House. Even as Ukrainian officials have publicly been loath to criticize Trump’s pressure campaign on their country, frustrations with Washington have quietly percolated. And last weekend, they were especially acute.
