The US Court of Appeals for the District of Columbia Circuit on Wednesday ordered a federal judge to dismiss the case against former Trump advisor Michael Flynn.

The appeals court’s ruling supports the decision by the Department of Justice (DOJ) to abandon the case. Flynn, the former national security adviser to President Donald Trump, pleaded guilty on two occasions to lying to the FBI about conversations with the Russian Ambassador. Since then, there has been a long campaign by Trump and other officials to dismiss the case, with Flynn attempting to revoke his guilty plea.

Judge Emmet Sullivan had appointed a retired judge last month to challenge the decision by the DOJ to dismiss the case. The appeals court ruled 2-1 Wednesday that there was insufficient reason to question the DOJ’s decision, ordering that the case be dropped.
