On Tuesday (Aug. 11) Joe Biden announced Senator Kamala Harris as his running mate for the 2020 presidential election. Following the announcement, celebrities took to social media to send their congratulations and show their support for her.

“[Joe Biden] can unify the American people because he’s spent his life fighting for us,” Harris tweeted following the news. “And as president, he’ll build an America that lives up to our ideals. I’m honored to join him as our party’s nominee for Vice President, and do what it takes to make him our Commander-in-Chief.”

“I’ve known Senator @KamalaHarris for a long time,” Obama tweeted, alongside a touching message he penned to her. “She is more than prepared for the job. She’s spent her career defending our Constitution and fighting for folks who need a fair shake. This is a good day for our country. Now let’s go win this thing.”
