The Department of Homeland Security (DHS) has released its findings on the immigration status of federal prison inmates, as mandated in a controversial Executive Order signed during the President Trump's first week in the White House. The report reveals that of the 37,557 confirmed immigrants in the federal prison system, 35,334 (94%) of them are in the United States illegally - which means out of a total of 185,507, federally incarcerated individuals, over 19% are confirmed illegal immigrants - which, in 2014, cost U.S. taxpayers $1.87 billion to house. It should be noted that the 19% figure is based on known illegals in federal prison - while 58,766 individuals are "known or suspected" to be illegal. If we apply the 94% confirmed illegal rate to the "known or suspected" population, it brings the total number of potential incarcerated illegal immigrants to 55,240 - or 30% of federal incarcerations.
