Controversy surrounds former Vice President Joe Biden’s son Hunter relating to his conflict of interests in business dealings with Ukraine.

Hunter was serving on the board of a trade coalition from 2012 to 2018 that lobbied the Obama administration for extra money to the foreign power. At the time, his father Joe Biden was vice president, and in charge of dictating U.S. policy toward Ukraine.

Hunter was on the board of the U.S. Global Leadership Coalition (USGLC) and he allegedly also organized a State Department meeting for the group’s president. The USGLC and its affiliate, the Center for U.S. Global Leadership, that Hunter was associated with have mostly been ignored by the media when his business ventures have been mentioned.

This is despite the rumors surrounding the Bidens and corruption in Ukraine and China, especially the Ukrainian gas holdings Burisma. Lobbying disclosures have indicated that USGLC added a number of Ukraine-related bills to its lobbying portfolio at the same time Hunter was on the board of Burisma.

Rosemont Senega, Biden’s private equity firm, was dwarfed by all the others on the U.S. Global Leadership Coalition (USGLC) and its affiliate, the Center for U.S. Global Leadership. Hunter Biden has publicly referred to himself as a member of USGLC’s board, though he was technically a director of the Center for U.S. Global Leadership.

Rosemont Senega was only small in stature, but it had important connections through father Joe Biden. Hunter Biden’s partner Devon Archer was a former adviser on Obama Secretary of State John Kerry’s 2004 presidential campaign. A third partner, Christopher Heinz, is Kerry’s son-in-law.

Text messages that were disclosed in a criminal case waged against Devon Archer demonstrated how valuable high connections can be, “Hunter Biden works for [Archer]. So we’ve got the top-level politicos with us. All of my guys are as top tier as it gets,” a businessman named Bevan Cooney wrote in text messages released in Archer’s case. “You don’t get more politically connected and make people more comfortable than that.”

In 2014, reported Daily Caller, while affiliated with the groups, Biden joined the board of Burisma Holdings, a known corrupt enterprise. The company, owned by Mykola Zlochevsky, who served as minister of natural resources under former Ukrainian President Viktor Yanukovych, paid Rosemont Seneca, Biden’s firm, more than $80,000 a month, according to publicly available records.

At the time, Joe Biden was the go-to-man in the Obama administration in dealings with Ukraine. In 2016, with his son serving on the Burisma board, his father Joe Biden made threats to withhold $1 billion assistance to Ukraine, unless the prosecutor Viktor Shokin, who was investigating corruption in Burisma, was fired. He got his wish, and Ukraine got the $1 billion, provided by legislation for which the trade coalition had lobbied.

With Burisma’s reputation for corruption, the partnership of Burisma with Hunter Biden was questionable, given his father’s high-profile position.

The corruption in Ukraine, involving the Bidens was a focal point in the Democrat’s attempt to impeach President Trump. The president, in his July 25 phone call with President Zelenskiy was accused of abuse of power by asking the Ukrainian president to investigate corruption relating to the Bidens—Joe Biden being was a political opponent.
