Hillary Clinton moves Friday event from Georgia State to City Hall

Democratic presidential front-runner Hillary Clinton is moving her Friday event in Atlanta from Georgia State University to a smaller and more tightly controlled venue at City Hall.

Multiple people, in and out of the campaign, told The Atlanta Journal-Constitution that the 12:45 p.m. event was being moved several blocks south  to the old city council chambers in the iconic center of city government. The event is still open to the public.

The reason why it's moving is less clear. Could it be because of what happened earlier Thursday in South Carolina? At a fund-raiser in Charleston, a protester called on Clinton to explain, why she once "called black youth 'superpredators,'" just two days before Saturday's Palmetto State primary and less than a week before Georgia's March 1 primary.

It was a reference to a speech Clinton, then first lady, gave in 1996, of a crime bill passed two years earlier. At the time, Clinton said, according to The Washington Post:

"They are not just gangs of kids anymore. They are often the kinds of kids that are called 'superpredators.' No conscience, no empathy. We can talk about why they ended up that way, but first we have to bring them to heel."

Clinton, on Thursday, said she wanted to explain, but the protester had been removed from the room. Later, Clinton told the Post:

"In that speech, I was talking about the impact violent crime and vicious drug cartels were having on communities across the country and the particular danger they posed to children and families.  Looking back, I shouldn't have used those words, and I wouldn't use them today."

Moving from Georgia State's Student Center to City Hall allows Clinton to better control the audience. Which would also help prevent instances like the protest which happened on a visit to Atlanta in October, when Black Lives Matter demonstrators interrupted a speech she gave at Clark Atlanta University.

A person with knowledge of the move said it was switched to accommodate the schedule of Atlanta Mayor Kasim Reed, a Clinton supporter.

The person said schedules are fluid and that venue changes are par for the course. But the last-minute switch raises questions that the campaign wanted to more strictly control her events on the eve of the South Carolina primary, a must-win for Clinton's White House bid.
