Sen. Lindsey Graham (R-SC) has heaped praise on former Vice President Joe Biden before as the "nicest" person he's ever met in politics. In one clip that's gone viral in the past week, Graham is even brought to tears talking about Biden's sincerity and warmth. But, even so, Graham can't let this whole Burisma Holdings scandal go unnoticed. He's taken the lead on getting answers.

I love Joe Biden as a person but we are not going to give a pass to what is obviously a conflict of interest.



I believe Hunter Biden’s association on the Burisma board doesn’t pass the smell test.



If a Republican was in the same position, they’d certainly be investigated! — Lindsey Graham (@LindseyGrahamSC) November 25, 2019

While Democrats are centered on the potential quid pro quo/bribery/extortion on the part of President Trump during his phone call with Ukrainian President Zelensky in July, Republicans like Sen. Graham are more interested to get to the bottom of the Bidens' ties to Burisma, the corrupt Ukrainian gas company of which Vice President Biden's son Hunter sat on the board.

In a letter last week, Sen. Graham officially requested documents from Secretary of State Mike Pompeo related to the Bidens and Burisma. Those include Biden’s calls with Ukrainian President Poroshenko, in which he reportedly asked for the removal of Prosecutor General Viktor Shokin, who was investigating Burisma, and Hunter's former business partner Devon Archer, who also sat on the Burisma board.

Biden was disappointed and ashamed in his old friend. He sent him a warning.

“Lindsey is about to go down in a way that I think he’s going to regret his whole life,” Biden told CNN's Don Lemon.

“I say: ‘Lindsey, I just — I’m just embarrassed by what you’re doing, for you. I mean, my Lord?” he continued.

“My conscious is clear," Graham said this week. "I love Joe Biden as a person, he is a really decent man. He's had a lot of tragedy in his life, but I have a conscious very clear right now, and I have a duty. If the House is going to shut it down the Senate is going to pick it up.”
