Biden accuses Trump administration of obstructing his national security team

President-elect says his advisers encountered roadblocks from the defence department and the office of management and budget

Joe Biden, the US president-elect, complained on Monday that his national security team has run into obstruction" and roadblocks" from political leadership at the Pentagon.

The criticism came after the defence department earlier this month suddenly suspended briefings with the Biden transition team, and with Donald Trump still seeking to overturn his election defeat.
