Feinberg is a major Republican donor. In 2016, he served on the Trump Economic Advisory Council during Donald Trump's presidential campaign, donated nearly $1.5 million to pro-Trump PACs, and co-hosted a $50,000 per person Republican National Committee and Trump fundraising dinner alongside other financiers. In February 2017, the New York Times reported that President Trump will assign Feinberg a role in the White House leading a review of the US intelligence agencies.
