On the boardwalk in Atlantic City, the holiday weekend began Friday morning with the chanting of disgruntled employees of the Trump Taj Mahal who walked off their jobs at 6 a.m.
Mr. Trump sued Trump Entertainment Resorts in 2014, demanding that his name be removed from the Taj and another Atlantic City casino, Trump Plaza. He later reached an agreement with Mr. Icahn to keep the Trump name on the Taj.
Mr. Icahn, whom Mr. Trump has suggested as a possible Treasury Department secretary in a Trump administration, also controls the Tropicana casino, which was the last of the casinos to come to terms with the union on Thursday.
