Kentucky Sen. Rand Paul (R) has some things to say about the way both Robert Mueller and Rep. Justin Amash (R-MI) have treated President Donald Trump as of late, and he appeared on Fox Business on Thursday to air some grievances.

“The thing that shocks me is that someone like Mueller, who is supposed to be esteemed and has been around for decades, completely and fundamentally misunderstands our justice system,” said Paul while talking to Stuart Varney.

“The burden on the government is to prove that you’re guilty. Nobody proves that you’re innocent. You’re presumed to be innocent,” he continued. “So he’s out there, all over television, saying, “We never said, we never concluded the president was innocent.” Completely misunderstands our judicial system. You’re presumed to be innocent; they have to prove you’re guilty.”

“He was not charged. He was not indicted, so he is innocent,” he concluded.

Paul went on to say that it’s not right to assume someone is guilty because they never said they were innocent, and that innocence comes with the lack of a guilty verdict. According to Paul, Mueller “completely misunderstands that.”

Varney then turned the conversation toward impeachment, which Paul said would be a complete waste of time and that the people are sick and tired of hearing about it.

According to polls, he’s not wrong.

However, you can’t bring up the impeachment of Trump without bringing up the recent calls for it by Amash. Paul wondered aloud why a libertarian like Amash would want to support an investigation undertaken by the secret FISA court going after Americans:

So I don’t understand a libertarian who would take this investigation and say we should pursue it and impeach the president. It goes against everything libertarians are for. We don’t like too much power. We don’t like the secret FISA court going after Americans. Foreigners are one thing, but always we’ve been very concerned about the FISA court being used against Americans. So I’ve been talking with the president. I spoke with him last night about how do we try to prevent this from happening to the next president or to the Americans at large? I think the president is open to trying to figure out a way, either legislatively or through executive order, we can try to prevent this abuse of power from happening again.
