Wagner, Ann, 1962-

Ann Louise Wagner (née Trousdale, September 13, 1962) is an American politician. A member of the Republican Party, she has served as the U.S. Representative for Missouri's 2nd congressional district since 2013. She previously served as the United States Ambassador to Luxembourg from 2005 to 2009.

Born in St. Louis, she earned a B.S.B.A. from the University of Missouri. After college, Ann went to work in the private sector and held management positions at Hallmark Cards in Kansas City and Ralston Purina in St. Louis. Wagner entered Republican politics in 1990, heading the GOP's efforts during the decennial redistricting of Missouri. In 1992, she was state director of President George H.W. Bush's unsuccessful reelection campaign. Wagner was elected to her first term of office as chair of the Missouri Republican Party in 1999, becoming the first woman to occupy the position. In 2001, Wagner took office as a co-chair of the Republican National Committee and helped preside over the 2004 Republican National Convention. On May 16, 2005, President George W. Bush nominated her as United States Ambassador to Luxembourg. On July 16, 2005, she was confirmed in the post by a voice vote in the United States Senate. After returning from Luxembourg, Wagner served as chair of Roy Blunt's 2010 U.S. Senate campaign. She unsuccessfully ran to become chair of the Republican National Committee in 2011.

In 2012, Wagner announced her candidacy for Missouri's 2nd congressional district after incumbent Representative Todd Akin announced his candidacy for U.S. Senate. In Congress, Wagner serves as Vice Ranking Member on both the House Financial Services Committee and House Foreign Affairs Committee. She has worked tirelessly to demand transparency and accountability from federal regulators, while continuing to investigate waste, fraud, and abuse. During her time in Congress, Wagner has been committed to regulatory reform, authoring bills such as the Retail Investor Protection Act which protects access to retirement savings for middle class families. She has made combating sex trafficking and online exploitation of women and children major legislative priorities. She authored the SAVE Act, which amended the Federal criminal code to allow prosecutions of those who knowingly advertise sex slavery, along with the Put Trafficking Victims First Act and the Allow States and Victims to Fight Online Sex Trafficking Act (FOSTA). FOSTA became law in April of 2018 and is the most significant anti-trafficking law Congress has passed in nearly 20 years, finally giving local, state, and federal prosecutors the tools they need to hold websites accountable when they profit from the sale of sex trafficking victims.
