The ongoing FBI investigation of Russia’s meddling in the 2016 presidential election just took a dramatic turn, with the first federal charges being approved by a federal grand jury.

According to CNN, the investigation led by special counsel Robert Mueller is picking up steam with authorities prepared for anyone charged to be taken into custody as soon as Monday. However, the details are not yet known as charges remain sealed.

Mueller, a former FBI director, was first appointed in May to lead the federal investigation into Russia’s effort to elect Donald J. Trump, and determine whether or not Russian officials conspired with members of Trump campaign.

In addition to the possibility of collusion, Mueller and his team have focused their investigation into obstruction on behalf of President Trump, who fired former FBI director James Comey, who once led the Russia investigation.

Subpoenas have already been issued to former Trump campaign chairman Paul Manafort, former national security adviser Michael Flynn, and others, including those involved in a Trump Tower meeting between Russians and campaign officials.
