A 180-year-old private Christian university in South Carolina is closing at the end of the semester after failing to raise $6 million to keep its doors open. Limestone University officials said that after two weeks of furious fundraising and other actions, they collected just a little over $2 million and had no choice but to close its Gaffney campus and online programs. “Our Limestone spirit will endure through the lives of our students and alumni who carry it forward into the world,” said Randall Richardson, chair of Limestone University's trustees.
