Georgetown University on Thursday announced measures to atone for having profited from the sale of nearly 300 slaves in the 19th century, giving an edge in admissions for their descendants. The US university's president, John DeGioia, will discuss the steps in a speech later Thursday in Washington, and is to offer a formal apology. Georgetown, a Jesuit school founded in 1789 in the US capital, is one of the oldest universities in the United States.
