Agencies critical to US security have suffered “enormous damage” at the hands of the Trump administration, US President-elect Joe Biden has said.
Mr Biden said his team was not getting the information it needed, including from the Department of Defense, as it makes its transition to power.
He spoke after a briefing by national security and foreign policy aides.
Mr Biden takes office on 20 January but President Donald Trump has refused to accept defeat in November’s election.
For weeks after the 3 November election, Mr Biden was blocked from receiving key intelligence briefings, an essential and normally routine part of a presidential transition. END
