The US State Department says 90 Americans who may have been impacted by the Nepal flooding disaster are unaccounted for. Brianna Keilar talks to Ashna and Shreya Ahuja who say their parents are among the missing after they traveled from their home state of Texas to go on a pilgrimage to Mount Kailash. The sisters tell Brianna "we hope that they have been found and are at a hospital and are safe."
