NEW: Trump says presidential immunity is ‘imperative’ or ‘you practically won’t have a country anymore’ after SCOTUS hearing

Trump said, "This is a trial that should have never happened. This is a case that should have never been filed. And it was really an incredible, an incredible day. Open your eyes. We can't let this continue to happen to our country."

He noted that a new report on the US economy had come out, which revealed that the economy is "doing very badly, the stock market's way down," and "some horrible numbers came out, including very high numbers on inflation and in particular gasoline, at seven and a half dollars in California, that usually leads the way, it's going to happen here too."

Trump also spoke on the Gaza Camp protests that have spread on college campuses across the nation, saying the protests are filled with "hate, anger."

"Biden is sending an absolutely horrible message. Horrible, horrible message. He has no idea how to message, he can’t speak, he can’t put two sentences together. He doesn't know what to do. This is not a president. This is somebody that shouldn't be doing what he's doing because he can't do it."

Biden, Trump said, "doesn't understand that all over the world we’re being laughed at as a country because of him and his administration."

Trump said he was forced to be at the Manhattan courthouse instead of the Supreme Court, but "I’m glad I was because it was a very interesting day in a certain way."

"But the US Supreme Court had a monumental hearing on immunity and the immunity having to do with presidential immunity. And I think it was made clear, I hope it was made clear, that a president has to have immunity. You don't have a president or at most, you can say would be a ceremonial president. That's not what the founders had in mind. And I'm not talking about ceremonial we want presidents to get things done and bring people together. So, I heard the meeting was quite amazing. Quite amazing. The justices were on their game.

"Presidential immunity," he added, is "very powerful, presidential immunity is imperative. Or you practically won't have a country anymore."
