The congressionally mandated agreement allows transition aides to work with federal agencies and access non-public information and gives a green light to government workers to talk to the transition team.
But Trump has declined to sign a separate agreement with the General Services Administration that would have given his team access to secure government offices and email accounts, in part because it would require that the president-elect limit contrbutions to $5,000 and reveal who is donating to his transition effort.
The agreement is a critical step in ensuring an orderly transfer of power at noon on Inauguration Day, and lays the groundwork for the White House and government agencies to begin to share details on ongoing programs, operations and threats. It limits the risk that the Trump team could find itself taking control of the massive federal government without briefings and documents from the outgoing administration.
Trump chief of staff-designate Susie Wiles met with Biden's chief of staff Jeff Zients at the White House on Nov. 19 and other senior officials in part to discuss remaining holdups, while lawyers for the two sides have spoken more than a half-dozen times in recent days to finalize the agreement.
