According to CIS.org approx 46% of deportees are return offenders. That is ONLY counting the ones that are arrested for committing a crime. Obama's policy is to only deport criminals. So, if you round that up to 50% because not all returnees get caught, then even with the benefit of doubt, only one million were technically removed. So, an estimated 700,000 enter the U.S. every year then eight years of Obama equals 5 million 600K minus the one million(2 mil minus 50%) that were deported. So, during Obama's watch, we have 4.5 million more illegals in our country.

We won't get into how many other presidents have allowed to cross the border. However, we have had three presidents that have rounded up illegals and bused them across the border.
