Hunter conned them.

As VP, Biden didn't have the power you suggest. Hunter could not affect the VP schedule or policies.

Mr. Archer debunked an anonymous, unverified allegation that Republicans have trumpeted for months that Mr. Biden, while vice president, and Hunter Biden each accepted a $5 million bribe from an official with the Ukrainian energy company Burisma.
Mr. Archer, who sat on the Burisma board along with Hunter Biden and handled his payments from the company, told lawmakers that he had never heard of any such transaction, and said the claims were most likely false boasting.
That testimony was consistent with evidence put forth recently from Lev Parnas, an
associate of Rudolph W. Giuliani, who served as the personal lawyer to Mr. Trump and who was assigned to dig up dirt on the Bidens in Ukraine.

Mr. Archer also undercut another Republican argument that the elder Mr. Biden had pressured Ukrainian officials
in 2016 to fire Viktor Shokin, the former prosecutor general of Ukraine, because he was investigating the company.
On the contrary, Mr. Archer said, he heard from associates in D.C., that Burisma had Mr. Shokin “under control” and that his replacement could be more damaging to the company.

Mr. Archer testified that he could recall about 20 times when he and Hunter Biden were meeting with business associates, and Hunter Biden put his father on speakerphone. The conversations, Mr. Archer said, were only about niceties — “How’s the weather? How’s the fishing?” — but he said the signal from Hunter Biden was clear.
“There was not business content in these conversations,” Mr. Archer told the conservative pundit Tucker Carlson in an interview after his testimony. “The idea of signals and influence — the prize is enough in speaking or hearing or knowing you have that proximity to power.”
