As his guests sampled short ribs and chocolate cake at a Dec. 1 reception held in Mar-a-Lago’s gilded ballroom and others mingled at another event held by the pool, U.S. Senate candidate Herschel Walker of Georgia raised more than $1 million for his campaign and an allied super PAC.

The following evening, Donald Trump dined at his private Florida club with about 20 couples, each of whom paid $250,000 to the Make America Great Again Again super PAC, a group run by close allies of the former president.

Two days later, Turning Point USA, a conservative group for young Americans, held a sprawling event at Mar-a-Lago, where organizers said Trump’s presence was the key to attracting 750 guests.

Since Trump returned from his New Jersey club to Palm Beach, Fla., this fall, Mar-a-Lago has become a hotbed for Republican fundraisers, with candidates jockeying to line the former president’s pockets in hopes of winning his endorsement, get a photo with him or simply give donors a chance to be in his presence.
