Ms. Sanchez unloaded on the president last week after he endorsed her opponent, Attorney General Kamala Harris, then followed up by suggesting in a Spanish-language interview that race may have been a factor.
“I think they have, what he said they have, is a friendship of many years. She is African-American, as is he. They know each other through meetings,” Ms. Sanchez said in the Friday interview on Univision 19, as translated by the Los Angeles Times.
The comment came after she issued a scathing statement Tuesday accusing Mr. Obama of supporting the “entrenched political establishment,” adding that he should have stayed out of the state’s first-ever Democrat-on-Democrat Senate race.
“I am disappointed that President Obama chose to endorse in a historic Senate race between two Democrats. I would think the leader of the Democratic Party would be focused on defeating Donald Trump and supporting Democratic Senate candidates against Republicans,” Ms. Sanchez said.
