Joe Biden once, not so long ago, considered Senator Lindsey Graham (R-SC) a friend and ally, but now the two men are at odds. The Washington Post reports:

Graham (R-S.C.) requested new documents Thursday from the State Department, attempting to uncover additional information related to Hunter Biden’s activities when he was on the board of the Ukrainian energy company Burisma.

The former Vice President spoke with Don Lemon last night about this “investigation” saying:

I am disappointed and quite frankly I’m angered by the fact he knows me, he knows my son. He knows there’s nothing to this. Trump is now essentially holding power over him that even the Ukrainians wouldn’t yield to.
