Former President Barack Obama and ex-first lady Michelle Obama took digs at President Trump during a three-hour ceremony celebrating their legacy at a new center in Chicago — alongside foreign dignitaries, Hollywood stars and other A-listers. Obama said in his remarks at a dedication ceremony for his new presidential center in Chicago that on the 250th anniversary of the American Revolution, it was important to remember how “radical the whole idea of self-government really was back in 1776.” “To that point, human history was a tale of conquest and caste and rigid hierarchies. A world where the strong dominated the weak, where power and wealth and status flowed through lineage, and the many were ruled by the few,” the 44th president said.
