Berman probably refused to approve the warrant application, so Rosenstein told him to recuse himself and approved them himself.
The warrant applications are sealed so nobody has any idea what fictions were used to create probable cause out of the Stormy Daniels allegations.
This is just more habitual legal abuse by the FBI. It’s how they operate, not just in DC, but in field offices all over the country.
The warrant applications may be sealed.... but surely Cohen demanded a copy of the Warrant issued for his “seizures”. They could not refuse him a copy of the Warrant.
Anything else and this is the Geheim Staats Polizei-== GESTAPO tactics.
