'Enormous damage' to US agencies by Trump - Biden
Agencies critical to US security experience suffered "enormous damage" as a result of the Trump administration, US President-elect Joe Biden offers said.
Mr Biden said his group was not getting the info it needed, including from the Department of Defense, since it makes its transition to power.

For weeks following the 3 November election, Mr Biden was blocked from getting crucial intelligence briefings, an essential and normally routine portion of a presidential changeover.

"The Department of Defense provides conducted 164 interviews with over 400 officials and provided over 5,000 pages of paperwork - far more than in the beginning requested by Biden's changeover team," he said.
A spokesman said the Pentagon had been "completely transparent" with the Biden crew.
In a speech following a video conference call with advisers which he submitted on Twitter, Mr Biden explained his team was facing "roadblocks" in the Department of Defense and any office of Management and Budget.
"At this time, we just aren't getting all the information that people demand from the outgoing administration found in key national protection areas," he said.
"It is nothing short, in my view, of irresponsibility."
The president-elect added that his team needed a "clear picture of our force posture around the world" and that US adversaries could exploit any confusion that resulted.
He said: "Many of the organizations that are critical to our secureness have incurred enormous destruction.
"Many of them have already been hollowed out on personnel, capacity and on morale. The policy functions possess atrophied or have already been sidelined."
Mr Trump sacked his Defence Secretary Mark Esper shortly after the election, apparently over Mr Esper's disagreement along with his contact to deploy the armed service against anti-racism protesters.
Mr Trump's subsequent installation of loyalists in the division was viewed with concern by political opponents, who saw it as an attempt to sow chaos in the ultimate weeks of his administration.
