Word of the aid freeze had gotten to high-level Ukrainian officials by the first week in August, according to interviews and documents obtained by The New York Times.
The problem was not a bureaucratic snag, the Ukrainians were told then. To address it, they were advised, they should reach out to Mick Mulvaney, the acting White House chief of staff, according to the interviews and records.
The timing of the communications about the issue, which have not previously been reported, shows that Ukraine was aware the White House was holding up the funds weeks earlier than United States and Ukrainian officials had acknowledged. And it means that the Ukrainian government was aware of the freeze during most of the period in August when Mr. Trump’s personal lawyer Rudolph W. Giuliani and two American diplomats were pressing President Volodymyr Zelensky of Ukraine to make a public commitment to the investigations being sought by Mr. Trump.
