Hunter Biden dialed his influential father "dozens" of times during meetings with his overseas business partners.

An eyewitness, Hunter Biden's former business partner and friend Devon Archer, is expected to share the details with Congress, the New York Post reported.

Archer allegedly witnessed Hunter put his dad on speakerphone during a meeting with executives from Burisma Holdings, the Ukrainian energy company that paid Hunter $83,000 a month.

Hunter Biden's phone calls

During the call, Hunter told his father that Burisma executive Vadym Pozharskyi and Mykola Zlochevsky, the company's owner, "need our support." Joe Biden responded with "vague pleasantries," the Post's Miranda Devine reported.

Archer also sat on the Burisma board. Hunter Biden's dealings with Burisma have long been a target for Republicans seeking to unravel the Biden family's shady tangle of international business deals.

Joe Biden has long denied any involvement, a claim that has become increasingly untenable.

According to a newly released FBI memo, Burisma executives told an informant that they kept Hunter Biden on the board to secure favors from his powerful father, who was steering U.S. policy in Ukraine at the time.

In exchange for $10 million, then-vice president Biden allegedly pressured Ukraine to fire prosecutor Viktor Shokin, who was investigating Burisma. Biden notoriously bragged about the firing in 2018, saying, "Well, son of a bitch. He got fired.”

Deny, deny, deny

Archer is scheduled to speak with the House Oversight panel on Monday, but it remains to be seen if he will appear before the committee - he has already cancelled three times. 

If he does show, he is also expected to speak about a Georgetown dinner Joe Biden attended in 2015 with Pozharskyi, the Burisma executive, who sent Hunter an e-mail after to thank him for the introduction.

The White House and its attack dogs in the Democratic party have dismissed the mounting evidence of Biden's corruption, saying it's all a Republican conspiracy theory.

Some observers have noted a tone shift in the White House's narrative, however, after press secretary Karine Jean-Pierre said Biden was "never in business" with his son. The language is softer than the administration's usual claim that Biden has never discussed his son's business.

"I've been asked this question a million times. The answer is not going to change. The answer remains the same: The President was never in business with his son. I just don't have anything else to add," she said.
