Holder, the first African-American attorney general, also notes that Clinton is in favor of tougher gun laws and "police accountability."

The 30-second spot, Clinton's first in South Carolina, comes a few weeks ahead of the Palmetto State's Feb. 27 primary. 

The ad airing this week is part of a broader ad buy in Charleston, Columbia, Greenville-Spartanburg and Florence-Myrtle Beach, according to Clinton's campaign. 
 
Holder was previously featured in a similar 60-second radio ad for Clinton released last week. He positions himself as a target of Republicans and ally of Clinton in the ads.
 
South Carolina holds the fourth voting contest after Iowa, New Hampshire and Nevada. Clinton is widely viewed as having strong support among black voters in South Carolina.
