Bixby regularly testifies before the U.S. Congress regarding the nation's fiscal policies, national budget plans, and budget deficits and government waste. He was a key member of the Coalition's Fiscal Wake-Up Tour, which began in 2006. The tour runs in conjunction with the Peter G. Peterson Foundation in cities around the country to educate Americans about the growing national debt. In a PBS News Hour program in November 2008, Bixby was introduced along with former Congressional Budget Office director Robert Reischauer as "two people who have long followed the budget, the lobbying, and the fights surrounding it, and all the fine print in between." During the segment, Bixby identified programs like Social Security, Medicare, and Medicaid as spending areas that should be reassessed because they "run on autopilot." Bixby also noted that "a lot of waste...is in the eye of the beholder...What is somebody's waste is somebody else's lifeline from the federal government." The Concord Coalition's efforts to raise public awareness, with Bixby touring across the nation, plays a key role in the 2008 documentary filmI.O.U.S.A. Bixby is frequently cited by the media, speaking on behalf of the Concord Coalition, on issues like the federal deficit and federal budget. He has been quoted by newspapers like the Washington Post on the fiscal impact of the 2010 federal health care reform bill, and the New York Times on how to address the national debt. At the start of 2009, he warned that the federal deficit would have serious long-term consequences and that certain policies like permanent tax cuts and expanding entitlement programs to deal with the recession would only drive the deficit up further. In January 2013, he was cited by the Chicago Tribune for his criticism of Congress’ dealing with the fiscal cliff crisis, stating that the congressional deal "solves no difficult problems." Bixby served as a member of the at the Bipartisan Policy Center.
