President-elect Donald Trump on Tuesday reached a required agreement with President Joe Biden’s White House to allow his transition staff to coordinate with the existing federal workforce before taking office on Jan. 20. 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. The White House agreement was supposed to have been signed by Oct. 1, according to the Presidential Transition Act, and the Biden White House had issued both public and private appeals for Trump’s team to sign on.
