So, there was a republican-led Senate investigation of Joe Biden and his work in Ukraine as vice president chaired by Sen. Ron Johnson, a close ally of President Donald Trump's

Lookit. An attempt at Poisoning the Well: http://www.fallacyfiles.org/poiswell.html
To poison the well is to commit a pre-emptive ad hominem strike against an argumentative opponent. As with regular ad hominems, the well may be poisoned in either an abusive or circumstantial way.

You went for the circumstantial path. That's needed to signal to your audience here that they can relax.

Hochstein has told associates that he never changed U.S. policy because of Burisma and was never asked to do so and that Burisma never factored into any policy decisions around energy or Biden's advocacy for a new Ukrainian prosecutor general.

Hmm. That's a convenient thing to say, but not really relevant to the point: Hunter Biden say on the board of Burisma despite having zero experience in energy. The minute he joined the board, though, Joe was a on plane:

Then-Vice President Joe Biden visited Ukraine on a mission to bolster the country's energy industry days after his son Hunter joined the board of natural gas company Burisma in 2014

Huh. How about that. Wonder what they were going to say?

He will speak about both the short- and long-term energy situation in Ukraine. As he arrives, there will also be a team on the ground from the United States, a team of experts working on the reverse flow issue. That team will be in Kyiv and then will travel also to Slovakia, Poland and Hungary to help address the issue of reversing the flow of natural gas to provide Ukraine with some measure of short-term supply of natural gas as they look to replenish their stores.

But also he'll discuss with them medium- and long-term strategies to boost conventional gas production, and also to begin to take advantage of the unconventional gas reserves that are in Ukraine.

Interesting. Tell me more!
Q Are you talking about --

SENIOR ADMINISTRATION OFFICIAL: Yes.

Q -- beyond economic assistance?

SENIOR ADMINISTRATION OFFICIAL: Well, there's a package of economic and energy and governance assistance that he'll be discussing. And we, as you saw, just recently announced a latest tranche of security assistance, nonlethal security assistance. And he'll have the opportunity to speak with the government about what more is needed and what more we could provide in the period ahead.

Q So there's a package that includes economic, energy and discussion of further security assistance. Is that right?

SENIOR ADMINISTRATION OFFICIAL: Well, the package I'm describing includes economic, energy and governance assistance.

Hmm. Wonder if there's any conflict of interest between having Hunter on the board and Joe discussing "packages" to assist with "unconventional gas reserves" in the Ukraine.

I seem to recall a 3 word phrase in Latin that the left was fond of not too long ago...

This guy definitely needs to be on the Epstein watch. BTW, the answer to your question is that Epstein's best buddy was Bill Clinton. He certainly flew on the Lolita Express a number of times. When are you going to denounce those flights and what he was doing on them?
