Five Democratic senators vying for their party's nomination to challenge President Donald Trump in 2020 fanned out across the country Saturday to meet voters.

Sen. Kamala Harris of California spent her second straight day in the pivotal early-voting state of South Carolina, holding a town hall meeting in Columbia, the capital. Also visiting the state was Sen. Elizabeth Warren of Massachusetts, who met with an estimated 800 voters in Greenville before heading to Georgia — an unusual early stop for a White House hopeful but one that signals Democratic hopes to make inroads in the South.

Sens. Cory Booker of New Jersey and Kirsten Gillibrand of New York both focused on New Hampshire. Booker made his first visit there since joining the race earlier this month, holding a question-and-answer session with more than 400 voters in Portsmouth.

Sen. Amy Klobuchar of Minnesota, meanwhile, visited neighboring Wisconsin before heading to neighboring Iowa, home to the nation's first caucus.

The New Jersey senator used his inaugural visit with prospective Democratic voters in the country's first presidential primary state to share his vision of politics emphasizing empathy and a "sense of common purpose."

The California senator visited a handful of female-owned businesses in Columbia, S.C., on the second day of a swing through the early-voting state. She stopped in Styled by Naida, a black-owned business, and bought a wide-brimmed teal hat.

Harris' visit was organized by Jennifer Clyburn Reed, whose father is Rep. Jim Clyburn, the third-ranking Democratic leader in the U.S. House.

Gillibrand told a crowd of about 450 people Saturday at Dartmouth College — her alma mater — that the president's worst offense since he was elected has been to "dehumanize people" and create a climate of fear and hatred, especially toward immigrants.

Top names yet to announce are former Vice President Joe Biden, Beto O'Rourke, a former Texas congressman, and Sen. Sherrod Brown of Ohio.
