Sen. J.D. Vance (R-OH) slammed left-wing NBC News host Kristen Welker during an interview on Sunday over President Joe Biden’s political prosecutions against former President Donald Trump.

Vance made the remarks during an interview on the network’s “Meet The Press” program when asked if Trump would go after the Biden family if he were to win in November.

“Well, first of all, Kristen, I find it interesting how much the media and the Democrats have lost their mind over this particular quote,” he said. “Donald Trump is talking about appointing a special prosecutor to investigate Joe Biden for wrongdoing. Joe Biden has done exactly that for the last few years and has done far more in addition to that to engage in a campaign of lawfare against his political opposition. I think what Donald Trump is simply saying is we ought to investigate the prior administration.”

“There are obviously many instances of wrongdoing,” he continued. “The House Oversight Committee has identified a number of corrupt business transactions that may or may not be criminal. Of course you have to investigate to find out. So I think Donald Trump’s saying, ‘look, let’s do the basic work of investigating wrongdoing,’ is a totally reasonable thing for him to do. And frankly, the Biden administration has done far worse. So if you think that what Donald Trump is proposing is a threat to democracy, isn’t what Biden has already done a massive threat to our system of law and government?”

Welker tried to absolve Biden from the controversy by noting that he did not directly hire the special prosecutor in the Trump cases.

“I have to reject the premise here. Joe Biden appointed the Attorney General, Merrick Garland, who of course answers to Joe Biden, can be fired by Joe Biden,” Vance fired back. “So the idea that the Biden administration has nothing to do with the appointment of the special prosecutor, I think, completely betrays a misunderstanding of how our system of government actually works. And of course, Kristen, we have to make this point, Kristen, that the prosecution of Donald Trump in New York, which I think now has fundamentally been thrown in doubt by this immunity case, one of the main guys was a Department of Justice official in the Biden administration who jumped ship to join a local prosecutor’s office to go after Donald Trump.”

When Welker again tried to downplay the ties between the Biden administration and the criminal cases against Trump, Vance fired back: “Well, Kristen, first of all you said that it happens all the time, that the number three person in the Department of Justice jumped ship to join a local prosecutor’s office to go after the president’s political opponent? I don’t think that’s ever happened in the history of American democracy. And I don’t think that we should legitimize it.”

Sen. Lindsey Graham (R-SC) said over the weekend that he has serious doubts about President Joe Biden’s ability to continue serving as president and that both the president and his line of succession need to take cognitive tests moving forward.

Graham made the remarks during a Sunday interview on CBS News’ “Face The Nation” while talking about the fallout from Biden’s disastrous debate performance.

“Most of us are concerned of the national security implications of this debate about President Biden’s health,” Graham said. “Most Democrats are worried about Biden winning the election. I’m worried about Biden being the commander in chief for the next four months. We’re having a meeting with NATO in Washington next week. On October the 7th, Israel’s attacked by Hamas. On October the 8th, President Biden gives an interview to the special counsel, where they determined him to be a nice man with a bad memory and you couldn’t convince a jury he did anything wrong.”

“I want those tapes released,” he continued. “So, what I would like to see is President Biden take a cognitive test. I think everybody going forward in the line of succession should have a neurological exam on a regular basis.”

Graham said that all nominees for president going forward should have to take neurological exams as part of an overall health examination that is released to the public.

“We need to make sure that the people who are going to be in the line of succession are capable of being commander in chief under dire circumstances,” he said. “Here’s what I worry about, that our allies see a compromised Joe Biden, that our enemies see a compromised Joe Biden, and I’m offended by the idea that he shouldn’t take a competency test, given all the evidence in front of us. He is not only in denial. This is a dangerous time for the American people to have somebody at the ship – leading the ship of state who seems to be compromised.”

A few minutes later he again reiterated his concerns about Biden, saying that he was “very concerned that this man is not capable of being commander in chief for four more months.”
