David M. Walker (U.S. Comptroller General)

On May 14, 2018, Walker withdrew his candidacy for Governor, following a poor showing at the Republican state convention. A month later, on June 14, 2018 he endorsed businessman Bob Stefanowski.

In 2017, Walker announced that he would explore running for Governor of Connecticut. He was eliminated from the race on the second round of voting at the State Republican Party Convention in May 2018.

On April 9, 2017, Walker announced that he would be establishing an exploratory committee to run for the Republican nomination for governor of Connecticut. Walker pledged to support term limits for the office of governor and said that gubernatorial candidates should run as a ticket, so then voters know who would be their leaders.

In the 2014 election, Walker unsuccessfully sought to become the Republican nominee for Lieutenant Governor of Connecticut. In Connecticut, the candidates for Governor and Lieutenant Governor run separately in the primary elections, but together as a ticket in the general election.

In the fall of 2012, the Comeback America Initiative led a campaign called the "$10 Million a Minute" Bus Tour. The tour covered about 10,000 miles and stopped at universities, technical colleges, businesses, and more in over a dozen states. The tour's goal was to bring national attention to the economic and fiscal challenges that face our nation and various nonpartisan solutions that should be able to gain bipartisan support.

Peterson was cited by The New York Times as one of the foremost "philanthropists whose foundations are spending increasing amounts and raising their voices to influence public policy". In philanthropy, Walker has advocated a more action-based approach to the traditional foundation: “I do believe, however, that foundations have been very cautious and somewhat conservative about whether and to what extent they want to get involved in advocacy.” David Walker stepped down as President and CEO of the Peter G. Peterson Foundation on October 15, 2010, to establish his own venture, the Comeback America Initiative.

He has authored three books, with the most recent one titled Comeback America: Turning the Country Around and Restoring Fiscal Responsibility (2010). He is a frequent writer and commentator, and is one of the main subjects of the critically acclaimed documentary I.O.U.S.A.. Critic Roger Ebert named I.O.U.S.A. one of the Top 5 Documentaries of 2008.

David Walker served as Comptroller general of the United States from 1998-2008. He was appointed by Bill Clinton. While at the Government Accountability Office (GAO), Walker undertook a number of transformational reforms within the GAO and the government that were widely recognized. He also achieved two pieces of GAO-related legislation, one of which changed the name of the agency from the General Accounting Office to the Government Accountability Office. Walker embarked on a Fiscal Wake-up Tour, partnering with the Brookings Institution, the Concord Coalition, and the Heritage Foundation to alert Americans of the country's long-term fiscal imbalance. Walker left the GAO to head the Peterson Foundation on March 12, 2008. Labor-management relations became fractious at the end of Walker's nine-plus year tenure as Comptroller general. On September 19, 2007, GAO analysts voted by a margin of two to one (897–445), in a 75% turnout, to establish the first union in GAO's 86-year history. At the same time, despite controversy over GAO's internal reclassification effort, GAO employees rated the agency as the second best place to work in the federal government.

In 2008 Walker was personally recruited by Peter G. Peterson, co-founder of the Blackstone Group, and former Secretary of Commerce under Richard Nixon, to lead his new foundation. The Foundation distributed the documentary film, I.O.U.S.A., which follows Walker and Robert Bixby, director of the Concord Coalition, around the nation, as they engage Americans in town-hall style meetings. Warren Buffett, Alan Greenspan, Paul Volcker, and Robert Rubin also appear.

In the national press, Walker has been a vocal critic of profligate spending at the federal level. In Fortune magazine, in 2008 he warned that "from Washington, we'll need leadership rather than laggardship". In another op-ed in the Financial Times, he argued that the credit crunch could portend a far greater fiscal crisis; and on CNN, he said that the United States is "underwater to the tune of $50 trillion" in long-term obligations.

Walker has received numerous leadership and public service awards. For example, Walker was awarded the American Institute of Certified Public Accountants' highest award, the Gold Medal Award of Distinction on October 19, 2008. In 2010 Walker was inducted into the Accounting Hall of Fame at Ohio State University.

Walker serves on the board of the Government Transformation Initiative Coalition. He previously served on various boards and advisory groups, including as Chairman of the United Nations Independent Audit Advisory Committee from 2007 to 2011, as a member of the Boards for the Committee for a Responsible Federal Budget, and the Center for the Study of the Presidency and Congress, as well as a member of Advisory Committees for The Public Company Accounting Oversight Board, the Peterson Foundation, and is a former member of the AARP's National Board and Policy Council. He is also a member of the National Academy for Public Administration, the National Academy of Social Insurance, the Trilateral Commission, and the Sons of the American Revolution. He is a National Co-Founder of No Labels previously served as Chair of a Postal Reform Panel for National Academy of Public Administration, and as Co-Chair of the Institute of Medicine's End of Life Panel.

Prior to his appointment to the GAO, Walker served as a partner and global managing director of Arthur Andersen LLP and in several government leadership positions, including as a Public Trustee for Social Security and Medicare from 1990 to 1995 and as Assistant Secretary of Labor for Pension and Welfare Benefit Programs during the Reagan administration. Before his time at Arthur Andersen, Walker was the Houston Director and then the Eastern Regional Director of Source Finance based in Washington, DC, and before that was in human resources at accounting firm Coopers & Lybrand.
