A US official who ordered the closure of lanes on a congested bridge in New Jersey last September has claimed that Governor Chris Christie was aware of the move at the time. Mr Christie has repeatedly said he first learned of the closure last month.
New Jersey Governor Chris Christie said he is "embarrassed and humiliated" by conduct of some people on his team following a scandal over his staff's alleged role in shutting down lanes onto the busy George Washington Bridge to punish a mayor.
Christie said, "There is no doubt in my mind that the conduct that they exhibited is completely unacceptable and showed a lack of respect for the appropriate role of government and for the people that we are trusted to serve".
Christie, a possible Republican White House contender, held a news conference after he became enmeshed in the scandal.
The Democratic presidential candidate may also have shown his cards on his choice of running mate.
The US president also shared a post on Twitter accusing Dr Anthony Fauci of misleading the public over hydroxychloroquine.
