He literally /never/ said "all illegal immigrants are rapists and murderers", stop watching lying, left-biased media.
He said he was going to deport all illegal immigrants, BUT he was going to START with the rapists and murderers. As in the ones in American prisons for those crimes, or the one with those crimes on their record in their home countries but currently living in America. And he said he was going to try and stop illegal immigration, but /especially/ by the people with those kinds of criminal records.
Jesus, look this shit up yourself and stop spouting the leftist propaganda.
