Obama Library

In this March 3, 2015 file photo, President Barack Obama, accompanied by first lady Michelle Obama, speaks in the East Room of the White House in Washington. The Barack Obama Foundation will hold a news conference Tuesday, May 12, 2015 in Chicago to announce where the president’s library will be built — the strongest confirmation yet that the city won the sweepstakes to erect the library.
