WASHINGTON — Former President Bill Clinton dined in Chicago on Tuesday night at the home of Fred Eychaner, the philanthropist, Newsweb Corporation chair and major Democratic donor. The dinner was at Eychaner’s Lincoln Park home, next to his Wrightwood 659 art and architecture gallery designed by the noted architect Tadao Ando. Eychaner is a longtime supporter of the Clinton Foundation, Hillary Clinton’s presidential bids and Democratic causes and candidates. The dinner was a fundraiser for the Clinton Foundation, with the attendees described by a source as “old friends getting together to support President Clinton and his foundation.”
