Donald Trump Makes Martin Luther King Jr. Birthplace a National Historic Park On Monday, President Trump signed the 'Martin Luther King Jr. National Historic Park Act' into law, upgrading the national historic site to a national historic park. Trump signed the law on the Air Force One with the civil rights leader's niece, Alveda King, in attendance. The former historic site will now expand to include the Prince Hall Masonic Temple. This important historical park tells his story, and this bill will help ensure that the park continues to tell Dr. King's story for generations to come. Martin Luther King Jr. National Historic Park is the first of its kind in the state of Gerogia.
