Federal data that is available to the public, says there are 2 million undocumented immigrants living in the U.S. and the current White House administration has allowed another 300,000 to return, says Donald Trump the Republican presidential nominee in a speech on August 31.

Many people have since fact checked the claims made from Trump’s speech of 75 minutes that introduced his immigration plan that contains 10 points.

Trump used the undocumented immigrants’ numbers to argue the proposal he has made for zero tolerance for all criminal aliens. He has vowed to remove all of them from the U.S.

Trump proposed the return of all the aliens since the release of is immigration plan back on August 20 of last year. The “criminal aliens” are noncitizens that have been convicted of a crime.

Trump has cited federal data and said there are a minimum of 2 million people who are noncitizens and have been convicted of crimes living in the U.S.

The number is from a report from 2013 that says there were 1.9 million criminal aliens. However, that figure is referring to a broader group of noncitizens that have criminal records not the violent crime or terrorists that Trump refers to.

The list includes undocumented immigrants as well as people who are permanent residents and those on temporary visas.

People who are lawfully present in the U.S. who have been convicted of a serious crime are subject to officials removing them.

The exact amount of non-citizens illegally in the country within the figure of 1.9 million is unclear. One think tank that takes no position on legislation on immigration, estimates that figure to be just over 800,000 of the more than 1.9 million.

Trump also said over 300,000 undocumented criminals were released since 2013 by ICE, and were not detained or put in line to be deported.

The House Judiciary Committee was given ICE estimates for criminal conviction releases. Between 2013 and 2015, the estimate was at just less than 82.300 that ICE released into settings that were non-custodial.

The figures are far different from the 300,000 Trump used. The immigration problems in the U.S. have caused much uproar and Trump has used that to his advantage during his campaign, but time will tell if that will help him overall with votes or if in the end it will hurt.
