Senator Cory Booker opened his first trip to South Carolina as a potential presidential contender by blasting President Trump.

Senator Booker expressed concerns about the administration's handling of the Khashoggi affair.

He offered a long list of problems from the wealth gap between whites and blacks at Allen, a historically black college.

Sen. Cory Booker opened his first trip to South Carolina as a potential presidential contender Thursday by blasting President Donald Trump for wrecking America's standing on the world stage.

Speaking to reporters gathered at Allen University in downtown Columbia, the New Jersey Democrat expressed concerns about the Trump administration's handling of the disappearance of Washington Post columnist Jamal Khashoggi, who Turkish officials have said was murdered in the Saudi Consulate in Istanbul more than two weeks ago.

"I'm worried about efforts to cover this up," Booker said. "I'm worried about our administration being willing to just go along to get along because of a lot of the financial interests we might have."

Booker made his assessment after Secretary of State Mike Pompeo briefed Trump on his visit to Turkey. Pompeo said he told Trump the Saudi government should have more time to complete its own investigation.

The senator is just one of several potential White House contenders swarming South Carolina, which holds the first presidential primary in the South. He will speak later Thursday at a state party dinner in Orangeburg. Former New York Mayor Michael Bloomberg was in Columbia earlier Thursday for a fundraiser for local Democrats. California Sen. Kamala Harris and Vermont Sen. Bernie Sanders, who ran for the Democratic nomination unsuccessfully in 2016, are scheduled to be in the state Friday and Saturday, respectively.

Former Vice President Joe Biden was in the state last weekend.

At his first stop Thursday, Booker painted a dire-yet-hopeful image of a country that has long struggled to reach its potential.

"If America hasn't broken your heart, you don't love her enough," the senator told several hundred students at Allen, a private historically black college.

He offered a long list of problems from the wealth gap between whites and black and escalating college costs to mass incarcerations and the infant mortality rate.

But he didn't blame Trump. "The Republicans didn't do this to us. We did it to ourselves," he said, urging the mostly young audience to honor earlier generations of civil rights activists by voting.

Booker said afterward that he sees the 2018 midterms as a "reaction" to Trump that goes beyond the Democratic base. He cited enthusiasm among independent and even Republican women "who are outraged by what's going on."

While he didn't say when he'll announce his next political moves, Booker was quick to tell reporters of his connections to South Carolina, starting with his family vacationing in Hilton Head when he was a child. "My lineage goes down into the South and the same experiences that many African-Americans here have," he said, adding that he's a former mayor of "a majority black city" and "the only senator in Washington who lives in a majority black neighborhood."

The other two black senators are Republican Tim Scott of South Carolina and Harris, Booker's potential White House primary rival.

Advisers to Booker, Harris, and other potential Democratic hopefuls have said for months that they learned lessons from Democrats' 2008 and 2016 fights. In both those instances, the top contenders split overwhelmingly white Iowa and New Hampshire. But in 2008, then-Sen. Barack Obama trounced Hillary Clinton in South Carolina, largely on the strength of the black vote, and went on to sweep the rest of the South and amass a delegate lead he would never relinquish.

Clinton did the same thing to Sanders in 2016.
