Biden transition adviser Jen Psaki said Biden on Monday will receive his first presidential daily briefing, the regular briefing on the most sensitive intelligence offered to top US officials.

Biden had previously been blocked from receiving intelligence briefings as the General Services Administration did not ascertain that Biden had won the election while legal challenges from President Donald Trump's campaign against the vote continued.

That ascertainment came on Monday, lifting those roadblocks to cooperation.

Transition adviser Kate Bedingfield said the Biden team will begin briefings with the Trump administration on vaccine distribution, testing and the personal protective equipment supply chain on Wednesday.

Bedingfield said the team has been in touch with FBI and Department of Justice officials about coordinating expedited background checks for Biden's senior White House staffers and the cabinet nominees he announced on Tuesday.
