Former Colorado Gov. John Hickenlooper is wrapping up three days of campaigning aimed at reaching out to black voters, who are key to a Democratic presidential effort in southern states.

Hickenlooper said Saturday in Charleston, South Carolina, that he's making an effort to "meet people where they are" in getting to know the diverse electorate in states outside his own.

Hickenlooper this week addressed the Rev. Al Sharpton's National Action Network, using his speech to the group in New York to outline his record on policing. Hickenlooper suggested that the nation "shutter some prisons altogether." He then visited a lynching memorial in Montgomery, Alabama.

On Saturday, Hickenlooper met with two survivors of a racist attack on a historic black church in Charleston, South Carolina.

South Carolina is the first state on the primary calendar with a largely black electorate.

Elizabeth Warren says the Democrats running for president will have to do more than campaign on an anti-Donald Trump message if they want to take back the White House in 2020.

The Massachusetts senator says they'll have to explain their own vision for the future of the country.

Warren is visiting the early caucus state of Nevada. She tells about 500 people at a rally in a high school gymnasium in Reno that she has an ambitious agenda that would force billionaires to pay their fair share of taxes, strengthen labor unions and protect everyone's right to vote.

She says it's important to build a broad grassroots campaign in Nevada and other places now to have a chance to win next year.

Warren says that "if our message is 'not Trump,' it's not going to work."

Beto O'Rourke may be competing against Pete Buttigieg (BOO'-tuh-juhj) for the Democratic presidential nomination, but the former Texas congressman is still a fan of the South Bend, Indiana mayor.

O'Rourke says "I like him a lot" when he was asked about the fact that the two politicians have a similar message and profile, and may be competing for similar voters.

O'Rourke, who's making a series of stops in Iowa, says he likes the way Buttigieg is approaching voters and "the seriousness with which he answers questions, the thought that he's put into it. I think he's terrific."

O'Rourke made the comments while leaving a house party in the Des Moines area.
