(CNN) The unsealing Monday of the first indictments arising from Robert Mueller's investigation provides many valuable hints regarding the future direction of the special counsel's probe. The use of sealed indictments and Mueller's decision to do an 11-year look back into former Trump campaign chairman Paul Manafort's prior business operations will make President Trump's personal lawyers very nervous today. Will the special counsel do a similar look back to 2006 on any aspects of the Trump business empire now that the Manafort indictment has opened the door? As CNN reported Monday, Manafort and former Trump campaign official Rick Gates have turned themselves in to Mueller, who unsealed an indictment against them on 12 counts, including conspiracy against the US, conspiracy to launder money, being an unregistered agent of a foreign principal, and making false statements.Paul Callan: As the first indictments are unsealed, hints regarding the road ahead are beginning to emergePresident Trump may be concerned about whether the special counsel is looking into the operations of his business empire, Callan says
The president will not find solace or refuge in the pardon power of the presidency should the _ probe zero in on him by "flipping" witnesses with early indictments.
