US President Donald Trump has accepted that a formal transition can begin for US President-elect Joe Biden to take office.
Trump said he was recommending a key federal agency "do what needs to be done", even as he vowed to continue contesting the result.
The General Services Administration said it was acknowledging Biden as the "apparent winner".
Earlier, Biden's victory in the US state of Michigan was officially certified, in a major blow to Trump.
