John Dean, the former White House counsel for President Richard Nixon, said Friday that President Donald Trump's entire family could be facing legal scrutiny after Paul Manafort's guilty plea.


Dean is best known as a key witness for the prosecution in the Watergate scandal that brought down Nixon.

"Manafort has flipped!" he wrote on Twitter.

"The entire Trump family now in jeopardy," Dean added.

Manafort, the former chairman of President Donald Trump’s campaign, pleaded guilty Friday to conspiracy charges as part of special counsel Robert Mueller’s Russia probe.

Manafort's plea deal with Mueller's office includes an agreement to cooperate with investigators.
