Early word from House leadership aides is that their offices inside the U.S. Capitol are locked down, but all are safe.

“We’re fine, thank you,” a House Republican aide told TPM. “Currently ‘sheltering in place.’”

“All safe,” a House Democratic aide said. “No idea.”

“Yes, we’re ok,” a second House Democratic aide. “Don’t know, trying to find out.”

A third House Democratic aide told TPM that they believed the shooting had occurred on the south side of the Capitol.
