Senate rooms evacuated after possible asbestos exposure

The Senate press gallery and nearby rooms in the US Capitol have been evacuated because of possible asbestos exposure.
Officials from the Architect of the Capitol's office say they're investigating the possible exposure after workers discovered a broken air duct above the press gallery, which is on the third floor and adjacent to the Senate chamber.
The officials say they're not sure when the air duct broke.
A spokeswoman for the architect's office says the Senate chamber isn't affected. Erin Courtney says they've "shut off the air, repaired the duct and are testing the areas served by the air handler for air quality."

The Capitol's House side was temporarily closed in July 2014 after what officials called a "potential release" during asbestos abatement work.
