Kerry Kennedy testifies, says sleeping pill "overtook" her
Closing arguments will soon begin in the drugged driving trial of Kerry Kennedy, the daughter of the late Robert F. Kennedy. She says she can't remember driving on a New York highway in 2012, after mistakenly taking a sleeping pill. CBS News legal analyst Rikki Klieman, a former criminal trial lawyer, talks about the case with the "CBS This Morning" co-hosts.
