While there has been no official announcement, President Obama has selected the University of Chicago as the host of his presidential library, The Chicago Tribune and USA Today reported. Their reports followed other news reports that President Obama has picked a location in Chicago, but not necessarily one of those proposed by the University of Chicago. The University of Chicago has been the favorite from the start of the competition -- the Obamas lived in its neighborhood before he was elected president and both the president and first lady once worked at the university. But zoning disputes for a time appeared to be a major obstacle, leading to speculation that the library could end up at Columbia University.
