Donald Trump is not walking away from his feud with the National Football League (NFL) over whether or not players have the right to protest the national anthem. On Monday morning, Trump lashed out again on Twitter, but one of his closest friends in the league is not standing by his side.

Brady on Trump

Over the last 72 hours, the one story that has dominated the headlines news and social media has been the bad blood between Donald Trump and the world of sports. The former host of "The Apprentice" ignited the feud last Friday night while campaigning in Alabama for Luther Strange, the president's pick in the upcoming GOP run-off election to fill the Senate seat left vacant by Jeff Sessions.

It was at that time when Trump brought up the issue of football players protesting the National Anthem, before referring to them as a "son of a bitch" who should be fired. Since then, Trump has been vocal with his views on his Twitter account, but has been met with tremendous backlash from the majority of the mainstream media, as well almost all of the world of sports. In his most recent Twitter rant on Monday morning, Donald Trump continued his attack on the NFL, but lost the support of Tom Brady of the New England Patriots in the process, as reported by TMZ on September 25.

Taking to his Twitter account on Monday morning, Donald Trump doubled down on his attack on the NFL over the national anthem protests.

"Many people booed the players who kneeled yesterday (which was a small percentage of total)," Trump tweeted, before adding, "These are fans who demand respect for our Flag!"

The president went on to explain that his comments have nothing to do with "race," in an apparent response to repeated allegations of racism.

"It is about respect for our Country, Flag and National Anthem," Donald Trump added in a follow-up tweet, while noting, "NFL must respect this!" An hour later, the president then went on to tweet the hashtag "StandForOurAnthem."

Brady speaks out

Not long after Donald Trump sent out his latest tweets, his personal friend in Tom Brady appeared on the "Kirk & Callahan" radio show on WEEI.

When asked his thoughts about Trump's remarks, the future Hall of Famer replied, "Yeah, I mean, I certainly disagree with what he said and, you know, thought it was just divisive."

During the national anthem on Sunday, Tom Brady locked arms with his teammates in a sign of solidarity and elaborated on his decision. "I just want to support my teammates," Brady said, explaining that he was raised by his parents to help bring people together, not push them away and create a divide. The New England Patriots quarterback went on to praise his teammates, past and president, in a what appeared to be yet another push back at Donald Trump.
