They are lying about immigrants.

If you are using undocumented immigrants' tax records to find and kidnap them, then it was never about them paying taxes. If you are showing up at their place of employment, then it was never about them not working. If you are showing up at courthouses, then it was never about getting them to "do it the right way". If you are kidnapping women and children, then it was never about criminals. If you're refusing to give them due process, then it was never about the Constitution. If you are building concentration camps in Florida to keep them here in cages, then it was never about the border. If you're spending billions to do this, then it was never about the economy. And if you're doing all this in the name of a 34 time convicted felon, then it was never about following the law.
