In a reflection of how serious the administration is taking the matter, sources tell The Daily Beast there are currently efforts underway to organize a legal defense fund for White House staffers. Such a fund would help cover the legal bills associated with Mueller’s probe, which are expected to be large. A Washington white collar attorney told The Daily Beast that everyone questioned by Mueller will likely need to retain counsel. Those lawyers will likely bill between $500 and $1000 per hour.

In most cases, third parties can pay for federal workers’ legal defense funds. As The Daily Beast reported in August, Paul Manafort and Michael Flynn—two targets of the probe—are already facing significant financial strain because of high legal bills.
