After graduating from college, Miller was an aide on the United States House Committee on the Judiciary, a legislative director for former U.S. Senator John A. Durkin ; the Deputy Director of Personnel Management for Congressional Relations in the Carter Administration, and a legislative assistant for the Subcommittee on Immigration, Refugees and International Law. In the early 1980s, Miller acted as government relations director for Fragomen, Del Rey, Bernsen & Loewy, a nationwide law firm specializing in immigration. He was also president of Immigration Services Associates, a government relations firm based in Washington, D.C. He ran unsuccessfully for the Democratic nomination for a House seat in Virginia in 1984. He operated his own government relations firm, Harris Miller & Associates, with clients in high tech, agriculture and banking. In 1995, Miller became President of the Information Technology Association of America. Miller, representing ITAA, provided Congressional testimony in favor of increases in the H-1B visa quotas and supporting the internationaloutsourcing of IT work. Because of this, he came under fire during his later Senate campaign from an IT worker association and organized labor groups. From 2007 to 2011 he was president of the Career Colleges Association, the umbrella government relations group for 1,400 for-profit vocational schools in the United States. Miller has been a friend and business associate of former Governor Mark Warner. He has served as President of the Northern Virginia Board of Governors for Virginia Opera. He also serves on the board of trustees of the Code of Support Foundation, a nonprofit military services organization.
Campaign for Senate
Miller was the first to announce a bid to be the Democratic candidate for the U.S. Senate against first-term Republican Senator George Allen. While his support was strong among the local Virginia party activists who weigh heavily in primaries, it was not enough to triumph over his late-entering primary opponent, James Webb, who benefited from a strong military background, the support of well-known blogs such as the Daily Kos, and the endorsements of several national Democratic leaders. These endorsements for Webb, including that of Chuck Schumer, head of the Democratic Senatorial Campaign Committee, were unusual for a primary and reflected Webb's perceived strengths as a candidate over Miller's. One newspaper columnist dismissed Miller as "a Republican strategist's dream opponent. He's as charismatic as a toaster, wonkier than Al Gore and as proudly liberal as Al Franken. And at just about the worst time ever to be one, he's a lobbyist. He's a total contrast to Allen; no cowboy boots or chewing tobacco here." The primary campaign was occasionally acrimonious, with Miller faulting Webb as a Democrat-come-lately who in 2000 voted for George W. Bush and endorsed Allen, and Webb criticizing Miller as an IT lobbyist who exported American jobs, at more than one point saying, "you've been called the Antichrist of outsourcing." After his loss, Miller affirmed his support for Webb as the Democratic candidate in the upcoming general election. He said he had "no regrets" and was taking some time off to think about his next move.
