Trump goes off rails on unscripted rant while pushing spending bill on Capitol Hill

President Donald Trump went on an unhinged anti-Joe Biden rant while talking about his "big, beautiful bill" on Capitol Hill — as House Speaker Mike Johnson stood by his side nodding on Tuesday.

The president stopped to talk with reporters on his way to speak with Republican lawmakers about getting the bill passed, as several hard-line Republicans continued to hold out against it.

Trump was in the midst of praising Senate Majority Leader John Thune (R-SD) about how he has rallied the Republican Party to support the bill.

"We're going to have a bill. The one big, beautiful bill. I think it's going to be, it's the biggest bill ever passed and we got to get it done. Tremendous tax cuts for people, tremendous incentives, tremendous regulation cuts, all these regulations that are so horrible," Trump said.

He then devolved into spewing theories about former President Biden and promising to investigate who signed legislation with the "autopen."

"And now you find out what happened. Because Biden — look, it's a very sad thing what happened," Trump said, presumably about Biden's recent stage-4 cancer revelation.

"But I really — we're going to start looking into this whole thing with who signed this legislation, who signed legislation opening our border. I don't think he knew! I said, there's nobody that could want an open border. Nobody. And now I find out that it wasn't him. He opened it. Who was operating the auto pen? This is a very serious thing. We had a president that didn't sign anything. He had almost everything. He opened the borders of the United States of America, and I kept saying, who would do such a thing? Allowing criminals to pour in from all over the world, not just South America — all over the world.

"They came in from Africa, they came in from Asia, they came from the Congo, the prisons in the Congo, in Africa. These are rough, rough people. The prisons from the Congo are empty. You know where they are? They're in this country. Who would sign this? Nobody would sign it. No sane person would sign it. You know who signed it? Radical left lunatics that were running our country and the autopen signed it.

"And they didn't want him," Trump said of Biden. "And they were disappointed in getting him because they wanted Bernie Sanders. And then after about two weeks, they said, 'Wait a minute, this is a gift. He'll do anything. We're going to use the autopen.' And they use the autopen and everything. He didn't approve this stuff because when Joe Biden was with it, he would never have approved that. You take a look. he would have never approved open borders."
