Background and career
Thomas Harold Massie (born January 13, 1971) is an American politician. A member of the Republican Party, Massie has been the United States representative for Kentucky's 4th congressional district since 2012. Raised in Vanceburg, Kentucky, Massie earned two degrees from the Massachusetts Institute of Technology, where he worked on computer simulation. He later founded a startup based on that work, returning to Kentucky after selling the company. In 2010, Massie was elected judge-executive of Lewis County. A libertarian Republican, Massie was first elected to Congress in a 2012 special election with the backing of the Tea Party movement. His staunch opposition to increases in federal spending, reauthorization of non-warrant surveillance programs, and interventionism have earned him the nickname "Mr. No". During President Donald Trump's second administration, Massie drew national attention for his disputes with Republican leadership over the One Big Beautiful Bill Act and the Epstein Files Transparency Act. He ran for re-election in 2026 in what was the most expensive U.S. House primary in history, losing renomination to Ed Gallrein, the Trump-endorsed candidate.
Massie was born in Huntington, West Virginia. He was raised in an Appalachian American culture in Vanceburg, Kentucky. His father was a beer distributor. He met his first wife, Rhonda, at Lewis County High School in Vanceburg. Massie earned a Bachelor of Science in electrical engineering in 1993 and a Master of Science in mechanical engineering in 1996 from the Massachusetts Institute of Technology. His master's thesis was titled, "Initial haptic explorations with the phantom: virtual touch through point interaction." He participated in the MIT Solar Electric Vehicle Team in 1990, helping to build the team's car, Galaxy. In the team's first race in 1990, he was the driver for Galaxy in the 1990 GM Sunrayce, finishing at Churchill Downs after ten days, winning sixth place. In 1992, Massie won MIT's then-named 2.70 ("Introduction to Design and Manufacturing", now named 2.007) Design Competition. MIT professor Woodie Flowers, who pioneered the 2.70 contest, mentioned that Massie watched this contest on television in seventh grade and wanted to come to MIT to win it.
In 1993, Massie and his wife founded a company, SensAble Devices Inc., that allowed users to feel digital objects that appeared on a screen, based on a technology he invented while in school. He completed his BSc the same year; his thesis was on the same topic, Design of a three-degree of freedom force-reflecting haptic interface. In 1995, Massie won the $30,000 Lemelson-MIT Student Prize for inventors and the $10,000 David and Lindsay Morgenthaler Grand Prize in the sixth annual MIT $10K Entrepreneurial Business Plan Competition. In 1996, his company was reincorporated as SensAble Technologies, Inc., after MIT's Bill Aulet joined him as a partner. He raised $32 million of venture capital, employed 70 people, and obtained 24 patents during his time at the company, which he sold in 2003.
In 2010, Massie ran for Judge Executive of Lewis County. He won the primary election, defeating the incumbent by a large margin, and then beat the Democratic nominee by nearly 40 points. Massie also campaigned for then–U.S. Senate candidate Rand Paul, speaking to various Tea Party groups on his behalf. Massie resigned as Lewis County judge-executive effective July 1, 2012.
In December 2011, Congressman Geoff Davis announced his decision to retire from his seat in Kentucky's 4th congressional district. Massie announced his candidacy on January 10, 2012. He was endorsed by Senator Rand Paul and Texas congressman Ron Paul. He was also endorsed by FreedomWorks, Club for Growth (which spent $500,000 on broadcast ads supporting him), Gun Owners of America, and Young Americans for Liberty. On May 22, 2012, Massie won the Republican nomination, beating his closest opponents, state representative Alecia Webb-Edgington and Boone County judge-executive Gary Moore, by a double-digit margin. In his victory speech, Massie thanked "the Tea Party, the liberty movement, and grassroots Ronald Reagan Republicans". He faced Democratic nominee Bill Adkins in the general election, and was expected to win the election by a wide margin. Massie resigned as Lewis County judge-executive effective July 1, 2012, to focus on his campaign for Congress and allow an election to be immediately held in order to replace him. He was succeeded by Lewis County deputy judge-executive John Patrick Collins, who was appointed temporarily by Governor Steve Beshear. On July 31, 2012, Congressman Geoff Davis resigned from office, citing a family health issue for his abrupt departure. On August 1, 2012, the Republican Party committee for Kentucky's 4th congressional district voted unanimously to endorse Massie as the party's nominee once a special election was called. Beshear called a special election to take place on the same day as the general election, November 6. This meant Massie ran in two separate elections on the same day – a special election for the right to serve the final two months of Davis's fourth term (within the lines that had been drawn after the 2000 census), and a regular election for a full two-year term (within the lines that had been drawn for the 2010 census). On November 6, Massie won both elections by a wide margin.
Massie was sworn in for the balance of Davis's term on November 13, 2012. He thus gained two months' seniority on the rest of the 2012 House freshman class. As a measure of how much the Cincinnati suburbs have dominated the district, he became the first congressman from the district's eastern portion in 45 years. Upon arriving in Congress he was assigned to serve on three committees: Transportation and Infrastructure, Oversight and Government Reform, and Science, Space and Technology. He later became chair of the Subcommittee on Technology and Innovation, replacing outgoing chair Ben Quayle. Massie broke from the majority of his party by opposing the reelection of Speaker of the House John Boehner, instead casting his vote for a fellow libertarian, Republican Justin Amash of Michigan. In May 2013, he voted against the Stolen Valor Act of 2013, which passed 390–3. In December 2013, he was the only congressman to vote against extending the 1988 Undetectable Firearms Act for another ten years. In March 2014, Massie voted against a bill to name Israel an American strategic partner. Massie voted no because the bill would have subsidized green energy companies in Israel. He said he would not support subsidies for American green energy companies, let alone foreign ones. The bill passed by a margin of 412–10, with 6 voting present. In May 2014, Massie objected to a voice vote to award golf star Jack Nicklaus a gold medal recognizing his "service to the nation", and demanded a roll call vote. The vote passed easily, 371–10. Through mid-June 2014, Massie had voted "no" at least 324 times in the 113th Congress – opposing one of every three measures that came to the House floor. Politico dubbed him "Mr. No". In 2015, Massie was the sole member of the House to vote "present" on the Joint Comprehensive Plan of Action, also known as the Iran nuclear agreement, citing Constitutional concerns that the treaties are not ratified by the House of Representatives and that he had no authority to vote for or against the nuclear deal. In November 2016, he voted against an extension of U.S. sanctions against Iran, the only member of the House to do so.
