"This morning around 7:15 a.m., Rep. Craig was assaulted in the elevator of her apartment building in Washington, D.C.," Coe said. "Rep. Craig defended herself from the attacker and suffered bruising, but is otherwise physically okay."

Coe added that there's "no evidence that the incident was politically motivated."

"Rep. Craig is grateful to the DC Metropolitan Police Department for their quick response and asks for privacy at this time," he said.
