Sen. Kamala Harris, D-Calif., speaks to members of the media at her alma mater, Howard University, Monday, Jan. 21, 2019 in Washington, following her announcement earlier in the morning that she will run for president. Harris, a first-term senator and former California attorney general known for her rigorous questioning of President Donald Trump's nominees, entered the Democratic presidential race on Monday. Vowing to "bring our voices together," Harris would be the first woman to hold the presidency and the second African-American if she succeeds. (AP Photo/Manuel Balce Ceneta)
