President Trump on Tuesday declared that he would release an unredacted transcript of his phone call with Ukrainian President Volodymyr Zelensky.

“I am currently at the United Nations representing our Country, but have authorized the release tomorrow of the complete, fully declassified and unredacted transcript of my phone conversation with President Zelensky of Ukraine,” he wrote on Twitter at 2:12 p.m.

”You will see it was a very friendly and totally appropriate call. No pressure and, unlike Joe Biden and his son, NO quid pro quo! This is nothing more than a continuation of the Greatest and most Destructive Witch Hunt of all time!” the president continued.

The tweets came as Biden’s campaign said the former veep planned to call for Congress to impeach Trump if the administration does not cooperate fully with ongoing House investigations and subpoenas.

Biden planned to speak Tuesday afternoon from his hometown of Wilmington, Delaware.

The phone conversation and possibly other issues became the subject of a whistleblower’s complaint that Trump pressured Ukraine to investigate Biden and his son despite a lack of known evidence that either Biden did anything wrong.

Congressional Democrats called the action an abuse of power, and charged that Trump was using US aid as a weapon to pressure Ukraine into digging up dirt on a political rival.

On Tuesday, the president said he ordered that military aid approved by Congress be withheld because he wanted other European countries to do more to support Ukraine, under threat from Vladimir Putin’s Russia, which invaded and later annexed Crimea.
