LAS VEGAS Democratic Congressman Steven Horsford of Nevada on Saturday acknowledged he had an extramarital affair with a woman who said the on-and-off relationship began in 2009 before ending last September. He is running for reelection in the swing district that leans Democratic and extends from Las Vegas through largely rural areas of southern and central Nevada. Linder told the the Review-Journal she was 21 and an intern for then-Sen. Harry Reid in his Las Vegas office when she met Horsford, then majority leader of the Nevada Senate. During the course of the relationship, Linder said, Horsford offered her financial support and introduced her to political connections. Linder said her sexual relationship with Horsford took place between 2009-10 and 2017-2019, though they remained in regular contact throughout the decade.
