Trump Campaign Aide George Papadopolous Pleads Guilty to Lying to FBI

Alan Dershowitz: Mueller Likely Hoping Manafort Charges Will Spark Chain Reaction

Preet Bharara suggested watching President Trump's reaction to the first charges in the Russia collusion investigation for anything that could be used against the president.

The former U.S. attorney fired by President Trump also recommended watching whether "the president of the United States is sending some kind of message to the potential defendant or other witnesses."

Former Trump campaign manager Paul Manafort turned himself in to the Washington, D.C. FBI office this morning on twelve charges including conspiracy against the United States and money laundering in Russia-related business deals.

"Special Counsel Mueller already has one criminal conviction. And this plea portends more charges to come," Bharara tweeted.

Manafort's indictment is a turning point in the investigation, and some warn it could be the first in a string of charges against others.
