The head of a Democratic lobbying firm says she was unaware of any involvement by Biden in his son's business deals

Republicans sought a transcribed interview with Karen Tramontano , CEO of Blue Star Strategies , as part of their impeachment inquiry against Biden .

Their chief accusation is that the Ukrainian gas company Burisma bribed Biden for a favor back when he was vice president during the Obama administration.

“I am also not aware of any financial arrangements or compensation to then Vice President Biden related to his son’s business dealings with Burisma or otherwise,” she said.
