The investigation of former Trump campaign chief Paul Manafort is gaining momentum. The "Washington Post" reports that FBI agents raided Manafort's Northern Virginia home last month. The "Post" calls it a pre-dawn raid that collected documents and other, unspecified materials. The July 26th raid came a day after Manafort met voluntarily with the staff of the Senate Intelligence Committee.  

The FBI is working with Special Counsel Robert Mueller in the investigation of Russia's interference in the presidential election, and possible collusion between Moscow and the Trump campaign.
