White House asked McGahn to say Trump didn't obstruct justice, but McGahn declined, source says

The White House requested that former White House counsel Don McGahn publicly state that President Donald Trump didn't obstruct justice, but McGahn declined, an administration official told CNN on Friday.

The timing of the White House's request -- which was made to McGahn's attorney William Burck through top White House lawyer Emmet Flood, according to the official -- is unclear.

The official and a separate source familiar with the matter said that McGahn previously told special counsel Robert Mueller's investigators he didn't believe Trump obstructed justice.
