WASHINGTON (AP) -- The chief of the U.S. Capitol Police has ordered an investigation into the force's response to Monday's mass shooting at Washington's Navy Yard.
Chief Kim Dine has asked the Capitol Police Board to conduct an independent review of the force's role in the aftermath of the shootings, in which 12 people and the gunman were killed.
The fact review team is expected to probe reports that one of the force's tactical response teams arrived within minutes of the shootings and were told by a supervisor to stand down. The British Broadcasting Corp. and other news outlets reported that a Capitol Police watch commander issued the order.
Dine directed the review team to report its findings by Oct. 21.
WASHINGTON (AP) -- Defense Secretary Chuck Hagel is ordering the Pentagon to review the physical security of all U.S. defense facilities worldwide and the security clearances that allow access to them.
Hagel is also tasking an independent panel to undertake the same reviews. He said Wednesday that "where there are gaps, we will close them."
Hagel ordered the reviews in response to Monday's shooting rampage at the Washington Navy Yard, where a dozen people were killed. The shooter, Aaron Alexis, was also killed.
Alexis, a former Navy reservist, had been undergoing mental health treatment from the Department of Veterans Affairs since August but was not stripped of his security clearance. The assault is raising more questions about the adequacy of the background checks done on contract employees.
