Democratic presidential rivals Tulsi Gabbard and Kamala Harris kept up the argument that began Wednesday evening during the Democratic presidential debate off-stage this week, as well.

Gabbard, a congresswoman from Hawaii who has been struggling in the polls among Democratic presidential contenders, took direct aim during Wednesday’s encounter at Harris’s record as a San Francisco district attorney and attorney general of California.

Gabbard not only continued that line of attack the next day, but amplified it, criticizing Harris’s racial credibility.

“Honestly, it’s pathetic that when confronted with the facts and the truth about her record that she claims to be proud of as a prosecutor, as attorney general of California, all she can do is lob cheap smears,” said Gabbard. “You know, the American people, voters deserve better than this, especially when her whole campaign is predicated on being a champion for the people, being a champion for black and brown people in this country who have been on the brunt end of racial injustice and an unjust criminal justice system for too long.

“This is all a lie because when she was in a position to do something about it, when she was in a position to make a difference and truly be a champion for the people, she furthered and perpetuated this unfair, unjust system that harmed many black and brown people in the state of California,” the congresswoman added.

For her part, Harris dismissed Gabbard’s jabs as a mere effort to raise Gabbard’s profile among voters.

“Well, I mean, listen, this is going to sound immodest, but I’m obviously a top tier candidate, and so I did expect that I would be on the stage and take hits tonight because there are a lot of people that are trying to make the stage for the next debate,” Harris said.
