Former House lawmaker and 2020 Democratic presidential hopeful Tulsi Gabbard unleashed on President Joe Biden on Monday over his promise to nominate a black woman to the Supreme Court.

The Hawaiian military veteran accused Biden of playing 'identity politics' with his pledge to seat the first black female justice -- and said he did the same thing when picking Vice President Kamala Harris as his running mate.

'Biden chose Harris as his VP because of the color of her skin and sex -- not qualification. She's been a disaster. Now he promises to choose Supreme Court nominee on the same criteria,' Gabbard wrote on Twitter.

She added, 'Identity politics is destroying our country.'

Biden is eyeing a list of potential candidates to replace retiring liberal Justice Stephen Breyer, who announced he'd step down last week after nearly three decades on the high court. 

He's using the 83-year-old's departure to fulfill a campaign promise of appointing a black woman to the bench, prompting swift backlash from Republicans who are concerned the president is putting race and gender ahead of picking the most qualified nominee.

But White House Press Secretary Jen Psaki at her Monday news briefing compared Biden's pledge to Ronald Reagan promising to and then appointing the first female justice.

'There was no such complaint from the voices on the right who are speaking out now,' Psaki said, adding: 'but there's no question in his mind that there is a wealth of qualified, talented black women to choose from.'
