Kamala Harris in 2019 FactCheck

On Crime: FactCheck: Denied DNA evidence in 1980s; backtracked in 2018

The context: Gabbard is referring to the case of Kevin Cooper, a Death Row inmate convicted of quadruple murder in 1983. Harris, during her tenure as attorney general, declined to use advanced DNA testing in the widely publicized case.

Last year, after the New York Times published an investigative piece on Cooper's case, then-Sen. Harris backtracked, saying, "I feel awful about this," and that she hoped the governor would order the testing. In February, Gov. Gavin Newsom ordered new tests. The results are pending.

On Crime: I chose the unpopular thing to NOT seek the death penalty

[Is that true? FactCheck by Vox.com:]

In 2004, as district attorney of San Francisco, she refused to seek the death penalty against a man convicted of shooting police officer Isaac Espinoza. She faced opposition from fellow Democrats; Sen. Dianne Feinstein called for the death penalty at the officer's funeral. But Harris didn't budge--an act of principle that cost her key political allies (as she received almost no support from police groups during her first run for attorney general in 2010).

On Education: FactCheck: Did not desegregate LA and SF school districts

The context: Yes, both districts have struggled to better integrate. But it was difficult -- and highly unusual -- for a state attorney general at that time to file suit to desegregate a school, said [a California schools expert].

A series of federal court decisions in the mid-1990s made it much tougher to bring desegregation lawsuits. Few state attorneys general even try. "There was nothing she could really do in San Francisco to force the district to use race-conscious efforts to desegregate the schools. The legal standard would be very difficult to prove," the expert said. "San Francisco has tried a lot of different things to make less segregated schools -- it's just a very difficult thing to do."
