WATCH: President Trump signs Antiquities order that could expand offshore drilling

Update: This event has ended.

President Trump is set to sign the Antiquities Executive Order on Wednesday, that could expand use of protected lands for drilling, mining and logging.

The order calls for Interior Secretary Ryan Zinke to produce an unprecedented review of America's national monuments, and could set the tone for Trump to question a to-date untested act of nullifying a previous president's establishing a national monument.
