President Donald Trump on Friday criticized New Orleans Saints Quarterback Drew Brees after he apologized for defending the American flag and the national anthem.

Trump said that he agreed with Brees’s earlier statement defending the national anthem.

“We should be standing up straight and tall, ideally with a salute, or a hand on heart,” Trump wrote. “There are other things you can protest, but not our Great American Flag – NO KNEELING!”

Brees apologized after he defended the American flag in an interview with Yahoo News.

He said:

I will never agree with anybody disrespecting the flag of the United States of America or our country. Let me just tell you what I see or what I feel when the national anthem is played and when I look at the flag of the United States. I envision my two grandfathers, who fought for this country during World War II, one in the Army and one in the Marine Corps. Both risking their lives to protect our country and to try to make our country and this world a better place. So every time I stand with my hand over my heart looking at that flag and singing the national anthem, that’s what I think about. And in many cases, that brings me to tears, thinking about all that has been sacrificed. … Not just those in the military, but for that matter, those throughout the civil rights movements of the ’60s, and all that has been endured by so many people up until this point. And is everything right with our country right now? No, it is not. We still have a long way to go. But I think what you do by standing there and showing respect to the flag with your hand over your heart, is it shows unity.

Trump said that Brees should not have apologized for his statement after the social media mob scolded him.

“I am a big fan of Drew Brees. I think he’s truly one of the greatest quarterbacks, but he should not have taken back his original stance on honoring our magnificent American Flag,” Trump wrote. “OLD GLORY is to be revered, cherished, and flown high.”

Brees apologized for his statement, after receiving heavy criticism from sports media and leftist activists:

In an attempt to talk about respect, unity, and solidarity centered around the American flag and the national anthem, I made comments that were insensitive and completely missed the mark on the issues we are facing right now as a country. They lacked awareness and any type of compassion or empathy. Instead, those words have become divisive and hurtful and have misled people into believing that somehow I am an enemy. This could not be further from the truth, and is not an accurate reflection of my heart or my character.
