(CNN) - Health Secretary Kathleen Sebelius said Tuesday that "we are definitely on track to have a significantly different user experience by the end of this month" with the problem-plagued Obamacare website.
In a conference call with state and local officials, Sebelius added that "this isn't a magic 'turn on the on switch'" to fix HealthCare.gov and that "the experience is vastly improved each day."
