First charges filed in Mueller investigation

A federal grand jury in Washington on Friday approved the first charges in the investigation led by special counsel Robert Mueller, according to sources briefed on the matter.
The charges are still sealed under orders from a federal judge. Plans were prepared Friday for anyone charged to be taken into custody as soon as Monday, the sources said. It is unclear what the charges are.
A spokesman for the special counsel's office declined to comment. The White House also had no comment, a senior administration official said Saturday morning.
On Friday, top lawyers who are helping to lead the Mueller probe, including veteran prosecutor Andrew Weissmann, were seen entering the court room at the DC federal court where the grand jury meets to hear testimony in the Russia investigation.
Reporters present saw a flurry of activity at the grand jury room, but officials made no announcements.

The special counsel's investigation has focused on potential collusion between the Trump campaign and Russia, as well as obstruction of justice by the President, who might have tried to impede the investigation.

Mueller's team has also examined foreign lobbying conducted by former Trump campaign chairman Paul Manafort, former national security adviser Michael Flynn and others. His team has issued subpoenas for documents and testimony to a handful of figures, including some people close to Manafort, and others involved in the Trump Tower meeting between Russians and campaign officials.

Last year, the Comey-led investigation secured approval from the secret court that oversees the Foreign Intelligence Surveillance Act to monitor the communications of Manafort, as well as former Trump campaign adviser Carter Page, as part of the investigation into Russian meddling.
