Donald Trump has fired back. Deadline reports the former host of The Apprentice has responded to the six former contestants who have publicly denounced his presidential campaign.

Trump hosted the NBC reality competition series between 2004 and 2015.

Earlier this week, six former Apprentice contestants came forward and publicly criticized Trump as “unpatriotic, anti-American, self-serving, regressive and downright lazy.” The group includes season 4 winner Randal Pinkett, who said:

As alums of ‘The Apprentice,’ we have had the opportunity to work with Donald in various capacities, including as employees of the Trump Organization. Based on that experience and Donald’s campaign, we do not believe he is worthy of becoming president of the United States.”

In response, Trump said it was “so sad,” calling the former contestants “six failing wannabes” who are trying “get back into the limelight like they had when they were with Trump.” He added that “nobody would know who they are if it weren’t for me.”

What do you think? Did you watch The Apprentice when Trump hosted? Do you think the contestants’ criticisms are fair?
