Keating Five DeConcini was widely noted as a member of the Keating Five in a banking and political contribution ethics investigation during the 1980s which grew out of the U.S. Savings and Loan Crisis. The Senate investigation involved Charles Keating and Lincoln Savings/Continental Homes, the sixth largest employer in the state of Arizona at the time. The Senate Ethics Committee looked into the actions of five United States senators in relation to their actions connected with Charles Keating and concluded that Senators DeConcini, McCain, Glenn, and Riegle "broke no laws or Senate ethics rules, but were aggressive in their actions on behalf of Charles Keating." Specifically, DeConcini was judged to have "acted improperly" and did not run for a fourth term.

In the 101st Congress, DeConcini served on the Senate Appropriations Committee, chairing the Subcommittee on Treasury, Postal Service and General Government. He also served on the Subcommittees on Defense, Energy and Water Development and Foreign Operations, and on the Senate Judiciary Committee, chairing the Subcommittee on Patents, Copyrights and Trademarks.

Although he claims he has not lobbied for harsher immigration laws and sentencing practices, he admits meetings with the Arizona Department of Corrections Director Chuck Ryan and "publicly speaking in favor of" for-profit prisons.
It was alleged that, in 1979, DeConcini had insider knowledge about the proposed route of the Central Arizona Project and that he used this knowledge to purchase land that he resold six years later to the federal government for a gain of almost $1,000,000.
