Robert Mueller is on an early winning streak.
Stacked with some of the country's premier prosecutors, the special counsel has beaten back a pair of preliminary attempts to block his subpoena power and limit who he can question as a potential witness. In July, Mueller's team also managed to win approval to execute a no-knock search warrant - unusual in a white-collar case.
But as the criminal case against former Donald Trump campaign officials Paul Manafort and Rick Gates speeds toward a possible spring 2018 trial, Mueller's team is bracing for an array of challenges to its authority.
The battle lines are already taking shape.













Comment: Despite early gains, Mueller may overreach himself in the long run. The outcome will prove a test of the integrity of the justice system. Time will tell.
