A month ago, just after Colin Kaepernick's protest against racial injustice hit the mainstream, the 49ers quarterback was told by Republican presidential nominee Donald Trump to leave the country. Clearly, Trump did not approve of Kaepernick's decision to kneel during the national anthem.

On Tuesday, a day after the first presidential debate between Trump and Democratic nominee Hillary Clinton, Kaepernick responded to those remarks.

He called Trump's comment "ignorant" and criticized Trump's campaign slogan, "Make America great again." According to Kaepernick, that slogan should read, "Let's make America great for the first time."

"That's a very ignorant statement that if you don't agree with what's going on here and if you want justice, liberty, and freedom for all then you should leave the country," Kaepernick said. "He always says, 'Make America great again.' Well, America has never been great for people of color. That's something that needs to be addressed. Let's make America great for the first time."

And here's what Trump originally said a month ago, via MyNorthwest.com:

Dori: "Are you following 49ers quarterback Colin Kaepernick refusing to stand for the anthem? He had bad things to say about both you and Hillary."

Trump: "I have followed it and I think it's personally not a good thing, I think it's a terrible thing. And maybe he should find a country that works better for him, let him try. It won't happen."

Kaepernick also wasn't a fan of what both Trump and Clinton said during the debate. He called it "embarrassing to watch."

Since Kaepernick's protest began, countless players around the league -- from Richard Sherman to Malcolm Jenkins -- have joined in. And Kaepernick has maintained he'll continue kneeling during the anthem until meaningful change occurs.

He also pledged $1 million to charities that help communities in need.
