The casino magnate Sheldon G. Adelson said on Thursday night that he would support Donald J. Trump now that he has become the Republican Party’s presumptive nominee.
“Yes, I’m a Republican, he’s a Republican,” Mr. Adelson said in a brief interview. “He’s our nominee. Whoever the nominee would turn out to be, any one of the 17 — he was one of the 17. He won fair and square.”
