The Department of State has granted Chris Miner the authority to handle matters related to immunity from judicial seizure for cultural objects brought into the United States for purposes like exhibition or research. This authority is based on existing laws and prior delegations and allows several senior officials, including the Secretary and Deputy Secretary of State, to also exercise these powers. The delegation will end when a new Deputy Assistant Secretary for Professional and Cultural Exchanges takes office, unless it is revoked sooner. The details of this delegation are set to be published in the Federal Register.
Simple Explanation
The State Department has asked Chris Miner to take care of special permissions that protect certain cultural items from being taken by courts when they're brought to the U.S. for things like shows or studies. This special job will later be given to someone else who will take over, but for now, Chris is helping out.
