This week has turned out to be eventful for GOP presidential hopeful Donald Trump. First, he made waves when he decided to boycott Fox News' GOP debate, and now he's announced an endorsement from an elected official that's sure to have him smiling. Republican South Carolina Lt. Gov. Henry McMaster has officially endorsed Trump, making him the highest-ranking South Carolina official to do so. McMaster introduced Trump before his rally Wednesday night in South Carolina and praised Trump's business achievements as well as his unwillingness to be controlled by donors, according to The Hill.
