GSA Administrator Elaine Murphy is Responsible for Calling the Election
“In accordance with the Presidential Transition Act of 1963, as amended, the GSA administrator ascertains the apparent successful candidate once a winner is clear based on the process laid out in the Constitution,” a GSA spokesperson told Government Executive on Friday. “The administrator’s ascertainment is done for the purposes of making services provided by the [transition act] available. Until an ascertainment is made, the statute allows for the Biden transition team to continue to receive the pre-elect services from the government (e.g., limited office space, computers, background investigations for security clearances). GSA has met all statutory requirements under the [transition act] for this election cycle and will continue to do so.”
