Story highlights Donald Trump's campaign launched a new ad hitting Hillary Clinton for describing his supporters as a "deplorables"

The ad will run in four battleground states backed by a $2 million buy

Baltimore (CNN) Donald Trump pounced Monday on Hillary Clinton for calling half of his supporters a "basket of deplorables" late last week, launching a new attack ad and arguing on the stump that the remark disqualifies Clinton from the presidency.

The Republican nominee, speaking Monday at the National Guard Association's annual conference, called on Clinton to apologize for and retract her remarks, arguing that she had "slandered" millions of Americans. Trump's outrage Monday was a significant political statement for a candidate who has repeatedly offended millions of Americans throughout his controversial campaign.

"The disdain that Hillary Clinton expressed toward millions of Americans disqualifies her from public service. You cannot run for president if you have such contempt in your heart for the American voter," Trump said. "You can't lead this nation if you have such a low opinion of its citizens."

Trump, who has not apologized for any of his political attacks or offensive statements throughout his presidential campaign, appeared shocked that Clinton had not yet apologized for her comments and called on her to do so.

"Hillary Clinton has not apologized to those she slandered. In fact, she hasn't backed down at all," Trump said. "If Hillary Clinton will not retract her comments in full, I don't see how she can credibly campaign any further."
