The first charges have been approved in the Russia investigation and someone could be taken into custody as early as Monday, CNN reports.
Special counsel Robert Mueller, who is leading the investigation into Russia's interference in the 2016 US election, has filed the first charges.
The investigation is also looking in to whether anyone in President Trump's campaign colluded with Moscow.
The charges are still sealed under orders from a federal judge, but plans have been made for an arrest, sources told CNN. It is not yet clear what the charges are.
The United States-Russia relationship became increasingly strained after US intelligence agencies concluded the Kremlin interfered in the election to discredit Hillary Clinton and help President Donald Trump win.
Russia has denied meddling in the election campaign.
