Senator Jeanne Shaheen says she supports a federal ban on assault rifles.
But Shaheen says more needs to be done to prevent tragedies like the one that happened in Newtown, Connecticut Friday.
Shaheen says there needs to be a comprehensive response to the school shooting.
Twenty-six people were killed in the shooting, including 20 children.
Shaheen says the nation must make sure mental health services are available for those who need it.
