A billionaire donor who bankrolled President Trump's 2016 campaign has been notably absent during his reelection efforts.
Robert Mercer, a hedge fund manager, donated upwards of $25 million dollars in the previous election cycle across multiple conservative efforts. So far, Mercer and his daughter, Rebekah, have made a single $355,200 donation to Trump's reelection effort.
Business Insider's David Levinthal reported that one of Rebekah's associates said "they're 100, 100, 100% out" which means they likely won't extend their support to the president in the few months left before November at a time when their monetary support could be key in swing states like Michigan and Florida.
In 2017, Jane Mayer of the New Yorker called Mercer "a brilliant computer scientist [who] helped transform the financial industry through the innovative use of trading algorithms."
