At an event in West Virginia on tax reform, President Donald Trump vents about the U.S. immigration system.

President Donald Trump's event Thursday, which was supposed to be about tax reform, swiftly turned into a rant about immigration policy and voter fraud, as the president tossed out his script — literally. "This was going to be my remarks," he said in West Virginia, holding up a piece of paper after his freewheeling comments. "It would have taken about two minutes, but, to hell with it," Trump said as he tossed the paper in the air. "Reading off the first paragraph, I said, 'This is boring.' Come on. Tell it like it is," he added.

Trump told horror stories that he tied to the U.S. immigration system as he pushed for change to immigration laws. He told a story about young girls never seeing their parents again after they get "cut up" by members of criminal gangs run by immigrants. He pointed back to comments he made in 2015 opening his campaign, in which he suggested "rapists" came from Mexico, to make an unsubstantiated claim that unprecedented rape was taking place as a so-called caravan of people moved toward the U.S. recently. "Remember my opening remarks in Trump Tower when I opened, everybody said, 'Oh he was so tough.' I used the word 'rape,'" Trump said. "And yesterday it came out where, this journey coming up, women are raped at levels that nobody's ever seen before. They don't want to mention that. So we have to change our laws." Trump claimed Democrats "like" mass immigration because they think immigrants will vote for them. He revived a false claim that "in many places like California, the same person votes many times."
