A federal grand jury brought new charges against President Trump's former campaign manager Paul Manafort Friday, alleging he secretly paid former European politicians to lobby on behalf of Ukraine, according to court documents.

Why it matters: Special Counsel Robert Mueller's Russia probe has been particularly active in the past week, culminating in Manafort's business partner Rick Gates pleading guilty earlier this afternoon.

Details: The superseding indictment contains five counts: conspiracy against the U.S., conspiracy to launder money, unregistered agent of a foreign principal, false and misleading FARA statements, and false statements.
