California Secretary of State Alex Padilla was chosen this week as the replacement for Vice President-elect Kamala Harris, according to an announcement from California Gov. Gavin Newsom.

While many praised Newsom's choice, advocacy groups and political leaders had spent months pushing the California governor to choose a Black woman for the spot, considering Harris is the only Black woman in the U.S. Senate. 

Advocates lobbied Newsom to choose either Reps. Barbara Lee or Karen Bass, two of the most powerful Black women in Congress. According to insiders who spoke to The New York Times, both were at the top of Newsom's list along with Padilla, a Latinx man. 

Aimee Allison, the founder of advocacy group She The People, slammed Newsom's decision in a statement to The 19th, telling the news outlet that "we need to keep marching forward and not reverse progress.”

“Sen. Harris cannot be the only woman of color at the table… It’s not enough for her to break this glass ceiling — there needs to be a path for future generations of women of color to follow in her footsteps. We cannot afford to wait decades for the voices of Black women to be heard,” she said. 

Politico reported that more than 100 women affiliated with Black Women United sent a letter to Newsom earlier this month pushing him to choose Lee or Bass for Harris' seat.  

“Black women have continuously been credited with saving the Democratic Party. By retaining the only seat held in the United States Senate by a Black woman, California has an opportunity to do more than just thank Black women,’’ the letter read.

“Congresswoman Bass and Congresswoman Lee, both of whom are seasoned policymakers and proven leaders, will hit the ground running to address the devastating economic impact and health effects of the COVID-19 pandemic,’’ it added.

Massachusetts Rep. Ayanna Pressley also called for Newsom to appoint a Black woman. 

"We absolutely cannot go backwards," the congresswoman wrote in a tweet last week. "With the election of Kamala Harris to VP-elect, California Governor Gavin Newsom must prioritize this leadership, perspective & representation in the vacated U.S. Senate seat & appoint a Black woman."

"Barbara Lee and Karen Bass are seasoned policymakers," she added.

Another group, Let’s Keep the Seat, also sent Newsom a letter making the same demand, calling the lack of Black women in the Senate "unacceptable."

One of the signers of that letter, state assembly member Shirley Weber, became Newsom's choice to replace Padilla as secretary of state. 

Harris was just the second Black woman senator after Carol Moseley Braun, who was the Senator for Illinois from 1993 to 1999.
