Background

Miller Strategies, LLC was established in 2017 by Republican strategist Jeff Miller, who ran the 2016 presidential campaign of former Texas Governor Rick Perry (R) and was a major fundraiser supporting Donald Trump’s 2024 presidential campaign. Miller Strategies found success in the first Trump administration, with clients like Altria Client Services, Valero Energy, Southern Company, the Pharmaceutical Research and Manufacturers of America, Broadcom Ltd., and Occidental Petroleum Corporation. While Miller Strategies’ revenues dropped during the Biden administration, its revenues increased by 40% when then-U.S. Rep. Kevin McCarthy (R-CA), a close friend of Jeff Miller, became Speaker of the House for a period in 2023. ²

Lobbying

Miller Strategies was hired by 79 clients in 2024, receiving more than $12 million in revenue to lobby on issues like taxes, trade, energy and nuclear power, health, finance, science and technology, and Medicare and Medicaid. Miller Strategies employed seven lobbyists that year and some of its largest clients included companies like Apple, Oracle, the PGA Tour, Cantor Fitzgerald, and Crypto.com. ³

As of June 2025, Miller Strategies had been hired by 109 clients in the year to date, receiving more than $8.7 million in revenue. As of June 2025, Miller Strategies’ largest clients of 2025 were HCBS Advocacy, the Blackstone Group, Zoom Video Communications, and Apple, and are focused on issues of human rights, securities, internet, and electronics manufacturing and equipment, respectively. ⁴

After the start of the second Trump administration, universities like Johns Hopkins, ​Cornell, and ​Northwestern have also hired Miller Strategies. Cornell, which has been particularly outspoken against the administration’s policies, has joined lawsuits aimed at reversing the Trump administration’s proposed cuts to expenses related to university grant funding. The presidents of Cornell and Northwestern both signed an April 2025 letter that claims that the administration is creating a “fear of retribution, censorship, or deportation” at universities among faculty, students, and staff. ⁵
