ROUGH CUT (NO REPORTER NARRATION)

STORY: U.S. President Barack Obama pledged on Wednesday that federal officials would oversee the response to U.S. Ebola cases in a more aggressive way, and said the Centers for Disease Control would send a "SWAT team" to any hospital encountering a new case of the disease.

After meeting with his cabinet for about two hours, Obama emphasized that the likelihood of a widespread Ebola outbreak in the United States was very, very low but said the international community must do more to help African nations struggling to control the epidemic.
