Donald Trump has put the NFL in his crosshairs once again ... blasting Roger Goodell for his now-famous apology to players -- and slamming the commish for insinuating he'd allow kneeling protests back in the league.
"I was surprised at Roger, Roger Goodell," POTUS said Wednesday, "that he would have done what he did and made this statement that he made. Nobody was even asking for it.”
The President made the comments on Fox News' "Hannity" ... saying he believes if Goodell does re-allow kneeling during national anthems, it'll cost him fans.
"That already happened before," Trump said. "I thought they learned their lesson. But, I think it's going to happen again."
"I saw him make this beautiful statement," Trump said of the Saints QB. "And, then the next day he retracted the statement. He talked about his father and his grandfather fighting in the war for our country, our flag, and then the next day he retracted it. I just don't get that."
