Democrats from across the party — including some of the women on Joe Biden's vice-presidential shortlist — are championing his historic appointment of Sen. Kamala Harris as his running mate.

What they're saying: "I warmly congratulate Senator Kamala Harris on her selection as Joe Biden’s Vice Presidential running mate," said former UN Ambassador Susan Rice, whom several sources said was in the top two. Senator Harris is a tenacious and trailblazing leader who will make a great partner on the campaign trail."

• Rep. Karen Bass, who was also being vetted by Biden, tweeted: "Kamala Harris is a great choice for Vice President. Her tenacious pursuit of justice and relentless advocacy for the people is what is needed right now. I worked closely with her when I was in Sacramento and she was the District Attorney in San Francisco. I continue to work closely with her here in Washington, DC as we push to reform our nation's policing system."
• House Majority Whip Jim Clyburn, who has been credited with reviving Biden's presidential campaign before the South Carolina primary, told MSNBC: "I am ecstatic. As you know, I'm the father of three daughters. I've been saying what a plus it would be to have an African-American woman on the ticket. I just think we are breaking ground here."
• Stacey Abrams, who was also being vetted for VP, tweeted: "I am privileged to have spoken with Vice President Biden at length over the weekend and again today. He is building a team that can rebuild America and restore our faith in what lies ahead."
• Andrew Yang, former 2020 candidate, said in a statement: "A vice presidential candidate who's leading the fight for cash relief for American families is exactly what our country needs right now. ... Senator Harris knows that, in this moment, the best thing we can do is invest in our people. I look forward to working with a Biden-Harris administration to get cash into Americans' hands."
• Aimee Allison, founder of She the People, a political group for women of color, said in a statement: ""Today is a spark of hope and a watershed moment for Black women and women of color. Her work to understand the struggles of the women of color leading the movement on the ground is what sets her apart in this critical moment."

The other side: The Trump campaign called Harris Biden's "political living will" and accused the new Democratic ticket of "surrendering control of our nation to the radical mob with promises to raise taxes, cut police funding, kill energy jobs, open our borders, and appease socialist dictators."
