Vicente Fox: Trump's Tacos are Fake!!!

Former Mexican Prez Vicente Fox scoffed at Donald Trump's Cinco de Mayo homage, saying it's outlandish to think any restaurant with a Trump connection can serve up authentic Mexican grub.

Fox goes on to praise Hillary Clinton to the skies, explaining why he thinks she'd make a great president.

Best part ... we shot the video on May 5th ... Fox was dining at an Italian restaurant!
