Bruce Maxwell, a rookie catcher, became the first athlete to protest during the national anthem in a Major League Baseball game Saturday.

Who is Bruce Maxwell?

Maxwell is the son of a U.S. military veteran, and was born on a military base. He plays for the Oakland Athletics.

Why did he do it?

Maxwell spoke to the San Francisco Chronicle to explain his actions.

“The point of my kneeling was not to disrespect our military or our constitution or our country,” Maxwell said. “My hand was over my heart because I love this country and I have family members, including my father, who bled for this country, and who continue to serve. At the end of the day, this is the best country on the planet. I am and forever will be an American citizen and grateful to be here, but my kneeling is what’s getting the attention, and I’m kneeling for the people who don’t have a voice.

“This goes beyond the black and Hispanic communities because right now we have a racial divide that’s being practiced from the highest power we have in this country saying it’s basically OK to treat people differently. I’m kneeling for a cause but I’m in no way disrespecting my country or my flag.”

What did the Athletics team do about this?

The Athletics official Twitter account posted a message of support for Maxwell after his actions.

“The Oakland A’s pride ourselves on being inclusive,” read the statement. “We respect and support all our players’ constitutional rights and freedom of expression.”

What was the reaction like?

Some, like black activist Shaun King, applauded the move:
