The filing, released near midnight Friday, marks the first official acknowledgment from the Trump administration that emails about the President's thinking related to the aid exist, and that he was directly involved in asking about and deciding on the aid as early as June.
The administration is still blocking those emails from the public and has successfully kept them from Congress.
Trump's decision to withhold nearly $400 million in US military aid to Ukraine as he pressed the country to investigate Hunter Biden and Joe Biden, his potential 2020 general election rival, are at the center of the President's impeachment trial.
Trump and his allies have repeatedly made unfounded and false claims to allege that the Bidens acted corruptly in Ukraine.
Senate Democratic Leader Chuck Schumer said in a statement on Saturday, "Every single Republican Senator voted to endorse the White House cover-up of these potentially important truth-revealing emails.
Make no mistake, the full truth will eventually come out and Republicans will have to answer for why they were so determined to enable the president to hide it.". »
