Vice President Kamala Harris visited a church in the Atlanta suburbs on Sunday, urging congregants to cast early ballots as part of her campaign’s “souls to the polls” push to turn out Black voters.

Sen. Raphael Warnock (D-Ga.) said Sunday that Democrats have to “keep doing the work” for Vice President Harris as concerns grow over Black voter turnout. Warnock joined CBS’s “Face the Nation” on Sunday morning and was asked by the host Margaret Brennan to weigh in on the lag of support for Harris among Black voters.

The pews were filling up inside Mount Zion Baptist Church, where former President Bill Clinton was set to launch his rural campaign swing for Vice President Kamala Harris in this Democratic stronghold bordering a sea of rural red Georgia.
