Senate Judiciary Committee Chairman Lindsey Graham (R-SC) on Saturday told CBS News' Margaret Brennan that even though he "loves Joe Biden" and the two are friends, he has to investigate what took place in Ukraine. After all, he can't go home to his constituents and say he looked the other way.

"You have announced a separate investigation into your friend Joe Biden and you said that you love him, but you want to pursue this investigation... He says you're going to regret this your whole life. Is there anything that you've done with this Ukraine investigation that gives you pause?" Brennan asked.

"No, not at all," Graham replied. "Joe Biden is a friend. He's one of the most decent people I've ever met in my life. But here's the deal: this whole process around the Ukraine reeks with politics. They've done everything but take a wrecking ball to Donald Trump and his family."

"We're not going to live in a world where only Republicans get looked at. As much as I love Joe Biden – and I am sincere when I say that – now that you want to talk about Ukraine, it's pretty hard for me to go home and tell my constituents to ignore the fact that Hunter Biden received $50,000 a month from a gas company in the Ukraine run by the most corrupt person in the Ukraine and two months after the gas company was investigated the prosecutor got fired," the Chairman explained. "I don't know if there's anything to this. I hope not. I hope I can look at the transcripts between the phone call between Biden and the Ukraine, Joe Biden, after the investigation began and say there's [nothing] there."

"These are legitimate concerns about what happened in the Ukraine. I love Joe Biden but none of us is above scrutiny," Graham said.

The former vice president is essentially upset that his buddy isn't turning a blind eye to his family's corrupt behavior. Graham absolutely has an obligation to get to the bottom of the corruption allegations so the American people know how their taxpayer funds are being spent and how politicians' families are benefiting from those transactions. This obligation isn't just to his constituents but to all Americans because of his position on the Senate Judiciary Committee.

At the end of the day, every politician's feet should be held to the fire. No one is above scrutiny or investigations. When we stop holding them accountable that's when our government becomes tyrannical.
