WATCH: Stephen Colbert Rips Trump's Embrace of Ike's Cruel Deportation Program

There were lots of lies, distortions and borderline insane moments at the GOP debate Tuesday night, but none were as offensive as Trump's defense of Eisenhower's 1950s program to expel Mexican immigrants from the United States.

After getting pushback from Jeb Bush and Marco Rubio about the "feasibility" of his plan to deport over 11 million undocumented Americans, Trumps defended it by citing President Eisenhower's 1955 mass expulsion of Mexicans which Trump insisted went off without a hitch. As Colbert noted last night, this is both untrue and terribly problematic. 

"I did some research," Colbert said. "Eisenhower did deport over a million Mexicans. It was a little program the United States government actually called 'Operation Wetback.' So, you might want to update that button to, 'I Like Ike... with significant reservations.'"

According to the Washington Post, "The tactical push from the U.S. Border Patrol was initiated by then-Attorney General Herbert Brownell, Jr., who told officers to shoot point-blank 'wetbacks' attempting to enter America."

The plan was devastating to the million of Mexican-Americans it affected. By citing it as inspiration for his plan, Trump is either ignorant of history or sending out a message that his views on immigration are from the 1950s. Either way, President Trump is a deeply troubling thought.
