Couple adopts 2 sets of twins to keep family together: 'We have a lot of love'

Karen and Tobias Thompson have seven adult children, 28 grandchildren and 3 great-grandchildren. When they found out their niece and nephew were having trouble at home, they took them in -- then found out their half-sisters were in the foster system and were constantly being moved around. The couple ended up adopting all four children to keep them together.
