A federal grand jury has approved the first charges in the Russia investigation being led by Special Counsel Robert Mueller, according to a report from CNN.
Citing sources who were briefed on the matter, "plans were prepared Friday for anyone charged to be taken into custody as soon as Monday," CNN reports.
The Mueller investigation is looking into Russian interference in the 2016 presidential elections and matters related to possible coordination between the Trump campaign and the Russian government.
The charges are currently sealed, meaning only those people who were in the room have knowledge of what transpired.
According to CNN, there was a "flurry of activity" at the Washington, D.C. federal court where the grand jury was convened.
Lawyers who are working with Mueller on the Russia investigation were reportedly seen entering the courtroom.
President Trump has repeatedly criticized the Russia investigation as a "hoax" and a "witch hunt." On Friday morning, Trump again tweeted his disapproval of the Mueller probe saying, "It is now commonly agreed, after many months of COSTLY looking, that there was NO collusion between Russia and Trump."
In August, multiple news outlets reported that Special Counsel Mueller had opened a grand jury, fueling speculation that there could soon be indictments for criminal charges.
At that time, a number of subpoenas were issued by the Washington-based grand jury. Reports indicated that some of the subpoenas were related to the business dealings of Trump's former National Security Adviser Michael Flynn. Others were related to a 2016 meeting between Trump campaign officials including Donald Trump, Jr. and a Russian lawyer.
Deputy Attorney General Rod Rosenstein appointed Mueller to lead the Russia investigation in May after Donald Trump fired James Comey, then the director of the FBI.
Rosenstein is overseeing all matters related to the Russia investigation. Attorney General Jeff Sessions had to recuse himself of handling the investigation due to his involvement as a campaign surrogate for Donald Trump.
In his letter appointing a special counsel to investigate Russian interference, Rosenstein authorized Mueller to look into any links or coordination between the Russian government and individuals associated with the Trump campaign and any matters that may arise from that investigation, including obstruction of justice.
