If the Times reporting is accurate, it means Trump was also aware of the whistleblower complaint when he told U.S. Ambassador to the European Union Gordon Sondland in September that there was no "quid pro quo" with Ukraine. The New York Times, which first reported this development, said it was known how much of the complaint was known to Trump.
The White House did not immediately respond to request for comment.
The Washington Post reported late Tuesday that two officials at the White House Office of Management and Budget resigned in part over concerns about Trump's order to withhold the Ukraine funds.
House Democrats allege that Trump, a Republican, abused his office by eliciting assistance from a foreign government to investigate a political foe whom he could face in next year's presidential election.
The transcripts released on Tuesday evening revealed that a lawyer for the White House's budget office resigned partly because of concerns overTrump's freeze on the military aid to Ukraine, according to a longtime career official from the office who had testified to Congress behind closed doors.
On Tuesday, House Judiciary Committee Chairman Jerrold Nadler, D-N.Y., announced the December 4 hearing and added that the committee meant to provide him with "certain privileges" while they consider "whether to recommend articles of impeachment to the full House". "Trump only released the aid because he got caught".
But the new timing detail shows he was also aware at the time that the whistle blower had accused him of wrongdoing in withholding the aid and in his broader campaign to pressure Ukraine's new President, Mr Volodymyr Zelensky, to conduct investigations on his Democratic rival for the presidency Joe Biden and his son that could benefit Mr Trump's re-election chances.
A previous anti-corruption probe that investigated Burisma Holdings, a gas company on the board of which Hunter Biden sat at the time, was shut down due to pressure from the elder Biden in 2016.
The revelation comes just days before the House judiciary committee takes over the impeachment inquiry, scheduling a hearing for next week as it pushes closer to a possible vote on charges of high crimes and misdemeanors and a congressional trial for the president in the Senate.
Trump promptly declassified what the White House claims is the full, unedited transcript of his telephone call with Zelensky, as he insisted there was nothing wrong in his dealings with Ukraine. "I hope that he chooses to participate in the inquiry, directly or through counsel, as other Presidents have done before him".
