Americans will be able to sign up on Oct. 1 for health insurance under Obamacare even if the government shuts down, White House deputy senior adviser for communications and strategy David Simas told reporters Wednesday.

"In terms of outreach, we are good to go," Simas said, speaking at the "Inside Politics with Bill Schneider" breakfast at the think tank Third Way. "On October first we will be up and running and people will be able to shop for a plan."
