Levin served as director of legal policy and the foundation's Washington-based Center for Civil Rights before becoming president in 1997. Under Levin's presidency, Landmark Legal filed a complaint with the Federal Election Commission in 2000 alleging that the National Education Association, the largest teachers' union in the U.S., did not disclose spending on political activity in Internal Revenue Service documentation. Landmark Legal also filed similar complaints with the United States Department of Labor in 2002 regarding NEA and political activity; by 2006, the NEA and smaller American Federation of Teachers had filed new documents with the Labor Department revealing over $100 million combined in political action spending. Following Freedom of Information Act requests in August 2012 of documents that would show if Environmental Protection Agency officials sought to delay regulations until after the 2012 presidential election, federal judge Royce Lamberth ruled in 2015 that although Landmark Legal did not establish that the EPA acted in bad faith, the EPA either carelessly or intentionally neglected Landmark's FOIA request. Lamberth previously ruled in 2013 that the EPA might have attempted to evade Landmark's FOIA request. In 2001, the American Conservative Union awarded Levin its Ronald Reagan Award for his work with Landmark Legal. Politico reported in 2014 that Levin received a salary of more than $300,000 per year as president of the non-profit Landmark Legal Foundation, whose donors include the Sarah Scaife Foundation, the Charles G. Koch Charitable Foundation and ExxonMobil. In 2018, Levin stepped down as president of Landmark Legal but remained on its board of directors. Radio broadcasting Levin began his broadcasting career as a guest on conservative talk radio programs. For many years, he was a contributor of legal opinions to The Rush Limbaugh Show, appearing more regularly as the Monica Lewinsky scandal developed. About this time, Sean Hannity became aware of him, and he began to feature in Hannity's radio show. Eventually, Levin gained a radio slot of his own on WABC, initially on Sundays beginning in 2002, then in the timeslot following Hannity's program in 2003. Cumulus Media Networks began syndicating The Mark Levin Show nationally in 2006. Levin has participated in Freedom Concerts, an annual benefit concert to aid families of fallen soldiers, and uses his radio program to promote aid to military families. Levin is also involved with Move America Forward, a charity that sends care packages to soldiers serving overseas. On February 11, 2016,
