Howard Lutnick, the CEO of the financial services company Cantor Fitzgerald, and Paul Singer, the president of Elliott Management, an investment management firm, both gave $5 million to MAGA Inc.

Annette Caldwell Simmons, the widow of businessman Harold Simmons, gave $2 million to MAGA Inc., while Warren Stephens, the CEO of investment bank Stephens Inc., gave $1 million.
