"I think there's a long history of sports figures doing so", said Obama during a press conference at the end of the G20 summit in the eastern Chinese city of Hangzhou.
Whether you're a sports fan or not, you've probably heard the name Colin Kaepernick in the news at some point during this past week.
"In terms of Mr. Kaepernick, I've got to confess that I haven't been thinking about football while I've been over here and I haven't been following this closely, but my understanding, at least, is that he's exercising his Constitutional right to make a statement", Obama said. Obviously, there's so much going on right now in America.
"I've been very blessed to be in this position and make the kind of money I do", the player, who will make a base salary of US$11.9 million this season with the 49ers, said last week. "My dad used to say, 'I may disagree with everything you say, but I'll fight to the death for your right to say it.' Mr. Kaepernick has every right to be wrong - but he's completely in the wrong".
I don't know when something officially qualifies as a movement, but the Colin Kaepernick National Anthem protest is gaining some steam.
"We need a more substantive conversation around race relations and the way people of colour are treated", she said after the game.
Personally, unless Kaepernick is literally flipping off the American flag or preventing others from participating in the anthem, I think he should be able to do what he wants.
Kaepernick said he meant to continue his protest into the regular National Football League season, which is scheduled to begin Thursday.
The reactions to Kaepernick's protest have been dramatic.
Kaepernick told reporters on August 28 that while the country had elected a black president "a lot of things haven't changed".
President Obama admitted the type of protest is hard for some to swallow.
Kaepernick, who made the team's 53-man roster, has been at the centre of a firestorm since his protest of the national anthem went public last month. "I love America. I love people".
Kaepernick's protests have garnered criticism and support alike.
Claiming that Kaepernick is exercising his constitutional rights and praising him for his sincerity and willingness to defend causes that he believes in, Obama has clearly shown his support for the quarterback.
