WASHINGTON, Sept. 24 (Xinhua) -- U.S. President Donald Trump said Tuesday that he authorized the release of the full transcript of a controversial phone conversation in July between him and Ukrainian President Volodymyr Zelensky.
Trump tweeted from New York, where he was attending the United Nations General Assembly session, that he has "authorized the release tomorrow of the complete, fully declassified and unredacted transcript of my phone conversation with President Zelensky of Ukraine."
"You will see it was a very friendly and totally appropriate call," he added.
The phone call, which happened on July 25 and is now under congressional investigation, has been at the center of the increasingly heightened tensions between Congress and the White House stemming from a whistleblower complaint filed in mid-August by an unidentified intelligence official, which alleged that Trump interacted inappropriately with a foreign leader and made an unspecified "promise."
The Wall Street Journal reported Friday that Trump pressed his Ukrainian counterpart about eight times in the phone call to seek information about business dealings between Democratic presidential candidate Joe Biden's son, Hunter Biden, and a Ukrainian gas company. The information could potentially be damaging to Biden senior's White House bid.
The Washington Post reported Monday that Trump told Acting White House Chief of Staff Mick Mulvaney in July to put almost 80 million U.S. dollars in military aid to Ukraine on hold, citing "concerns" about "a lot of corruption in Ukraine."
That order, which was subsequently passed on to lower-level officials, was made a week before the Trump-Zelensky phone call, according the Post.
Trump confirmed the delay of the military aid to Ukraine, telling reporters Monday that the decision was made because European countries did not pay their fair share to help the Eastern European country defend its national security.
Biden, who has adamantly denied having spoken with his son about the latter's overseas business, is expected to tell reporters later Tuesday that Congress has "no choice but to impeach" Trump if the president didn't comply with ongoing investigation, according to U.S. media reports.
"He's going to make the point that Trump's latest abuses are on top of all of his prior abuses," an aide with the Biden campaign was quoted by Politico as saying.
"He's going to call on Trump to comply with all of Congress' outstanding, lawful requests for information -- in the Ukraine matter, and in the other investigations. And if Trump does not comply, Congress has no choice but to impeach," the aide said.
