Watch: Trump supporter stumbles when asked to list a promise ex-president kept

The comedians of The Good Liars this week stumped a supporter of Donald Trump when they asked him to name a single promise that the former president had kept.

While talking to Trump supporters outside of a rally, Davram Stiefler asked a man what he thought about Trump.

"I love him!" the man replied. "We need him to save the country!"

Stiefler then asked the man specifically why he loved the former president.

"He did everything he said he was going to do," the man explained.

"So what are some of those things that he said and then he did?" asked Stiefler.

"Well..." the man said and then paused for several seconds.

"Maybe just one thing," Stiefler offered. "One thing he said and then he did."

"You caught me off guard there," the man acknowledged. "I don't know."

In fact, Trump failed to keep many of the promises that he made while on the campaign trail in 2016, including getting the Mexican government to pay for his still-unfinished border wall, repealing and replacing the Affordable Care Act, eliminating the national debt, and forcing pharmaceutical companies to charge less money for prescription drugs.
