From 2004 to 2006, Warren Rudman also led a team of attorneys that investigated accounting practices at Fannie Mae. Prior to the September 11 attacks, Rudman had served on a now oft-cited and praised national panel investigating the threat of international terrorism. He, along with fellow former Senator Gary Hart (D-CO), chaired the panel, and both Rudman and Hart have been lauded since September 11 for their prescient conclusions. Senator Rudman was an Advisory Board member and Co-Chair of the Partnership for a Secure America, a not-for-profit organization dedicated to recreating the bipartisan center in American national security and foreign policy. Warren Rudman was one of the few Jewish politicians elected in New Hampshire. He spent his final years as a resident of Hollis, New Hampshire, a suburb of both Nashua and Boston. He was the author of a memoir called Combat. Warren Rudman defeated incumbent John Durkin in the 1980 election, riding the wave of Ronald Reagan’s landslide victory. Durkin resigned and the Governor appointed Rudman to fill the vacancy in late December 1980. Rudman served on the Senate Appropriations Committee and the Ethics Committee. His best-known legislative effort was the Gramm-Rudman-Hollings Act.

Warren Rudman, along with John H. Sununu, was a key player in the appointment of Rudman’s personal friend, Supreme Court Justice David Souter, to both the First Circuit Court of Appeals and the Supreme Court. The Wall Street Journal later editorialized about the appointment, saying: “Mr. Rudman, the man who helped put liberal jurist David Souter on the high court” and who in his “Yankee Republican liberalism” took “pride in recounting how he sold Mr. Souter to gullible White House chief of staff John Sununu as a confirmable conservative. Then they both sold the judge to President Bush, who wanted above all else to avoid a confirmation battle.” Rudman wrote in his memoir that he had “suspected all along” that Souter would not “overturn activist liberal precedents.” Sununu later said of Rudman, “In spite of it all, he’s a good friend. But I’ve always known that he was more liberal than he liked the world to think he was.” After leaving the Senate, Rudman was twice considered as a possible Vice Presidential candidate on the ticket of two parties other than the GOP. In 1996, Ross Perot offered Rudman the slot to be his vice presidential running mate on the Reform Party ticket, but Rudman refused (as former Democratic Senator David Boren of Oklahoma did). Perot eventually selected Pat Choate.

Also, in 2004, Warren Rudman was mentioned as possible running mate for Democratic nominee John Kerry. Kerry eventually selected John Edwards. Rudman did accept Senator John McCain’s offer to serve as campaign chair in McCain’s 2000 presidential campaign. The Warren B. Rudman United States Courthouse in Concord is named for him. On January 8, 2001, he was presented with the Presidential Citizens Medal by President Clinton. He was a founder and Co-Chairman of the Board of Directors for the Concord Coalition. He was a co-chair, along with former Secretary of State Madeleine Albright and former National Security Advisor Sandy Berger, of Albright Stonebridge Group, a global business consulting and strategy firm based in Washington, D.C. He died of cancer on November 19, 2012. After his death, President Obama praised Rudman as an early advocate for fiscal responsibility. Coincidentally, his death occurred just slightly over a month after the death of John Durkin, his predecessor as US Senator from New Hampshire, whom Rudman defeated in 1980 when Durkin sought re-election. Durkin died on October 16, 2012.
