Manafort then resigned, two months after taking over amid questions about his alleged business ties in Russia and Ukraine. Manafort joins "CBS This Morning" to discuss the Trump transition -- including the consideration of Mitt Romney to be secretary of state -- and explains why he left the Trump campaign.
