Golden State Warriors coach Steve Kerr and Philadelphia 76ers coach Doc Rivers urged Americans to vote for Joe Biden over President Donald Trump in next week's election, appearing in a new advertisement for "The Lincoln Project" on Tuesday night. 

"We're at a crossroads, this country of ours, and it's time to decide where you stand," Rivers and Kerr say to begin a video clip shared over social media.

"I stand for truth over lies," Kerr says. 

"I stand for equality," Rivers says. 

"I categorically reject white supremacy," Kerr says. 

"I believe our veterans are true American heroes," Rivers says.

"Not suckers and losers," Kerr says.

The two NBA coaches continue in the video clip: "A vote for Donald Trump is a vote against the very ideals upon which our country was founded. Our democracy itself is at stake. So be a man. Take a good look in the mirror and decide, 'Is she worth defending?'

"We know where we stand. We stand united. We stand for the land of the free and the home of the brave. We stand with Joe Biden."

Kerr, a three-time NBA champion coach with the Warriors, has been one of Trump's biggest detractors from the sports world, most notably calling him a "blowhard" who was "ill-suited for the presidency" in 2017, while speaking out publicly against Trump's policies throughout the last four years.
