I've mentioned before that Trump is right on immigration. The US Government, especially the Obama administration, is nearly 100% derelict in it's duty to enforce immigration laws. But it's been poor for a long time. As a result, we've seen surges of illegal immigration. And catch and release has been the norm for a long time. Not enough is done to deport those with expired visas as the government is not tracking them and has no idea where they are. Even criminal illegal aliens are not getting deported.
