Republican presidential nominee Donald Trump invited players protesting the United States by refusing to stand for its national anthem to leave the country to find one better.

“Well, I think it’s a lack of respect for our country,” Trump maintained Monday on Fox & Friends. “I think it’s a lack of appreciation for our country, and it’s a very sad thing. I’ve never seen anything quite like it, actually.

“You know, you are talking about a major sport, maybe the major sport, and when you see that and it leads to a lot of other things. I think it’s a great lack of respect and appreciation for our country and I really said they should try another country, see if they like it better. See how well they’ll be doing. See if they are going to be making $20 million being a second-string quarterback.”

Four Miami Dolphins players joined Colin Kaepernick’s protest over the weekend by taking a knee during “The Star Spangled Banner.” Kaepernick, who called Trump a “racist” speaking to the press several weeks back, again refused to rise for the song on Monday Night Football.
