The Justice Department's internal watchdog says it will investigate how the department and its agencies prepared for and responded to last week's riots at the U.S. Capitol.
Listen to the briefing in our player above.
The investigation by the inspector general's office will examine whether information was appropriately shared by the Justice Department to other law enforcement agencies about the potential for violence.
The inspector general said it "also will assess whether there are any weaknesses in DOJ protocols, policies, or procedures" that hampered preparation and response to the events.
The review is one of multiple ones launched by inspectors general, including at the departments of Homeland Security and Defense and at the Interior Department, which oversees the Park Police.
The initiation of the review signals concern among the watchdogs that the preparations for, and response to, the breach of the Capitol by loyalists of President Donald Trump was lacking.
