FirstNet or the First Responder Network Authority was created by the Middle Class Tax Relief and Job Creation Act of 2012. DHS secretary, AG, and director of OMB are permanent board positions and the rest are chosen by Secretary of Commerce. 

Might be OK here since the permanent board members and commerce secretary Wilbur L. Ross was a POTUS pick.  Wouldn't hurt to dig on the others to be on the safe side though.

Also these people who are apparently not board members.

Michael Poth, CEO

Jeff Bratcher, Chief Tech and Ops

Jim Gwinn, Chief Info ofc

Frank Freeman III, Chief Admin Ofc

Kim Farrington, CFO

David Dasher, Chief Procurement
