Lawmakers are starting to look into the growing Ebola crisis on the African continent.

The House is convening a hearing tomorrow on combating the deadly Ebola virus. The top witness at the hearing will be Dr. Tom Frieden, director of the U.S. Centers for Disease Control.

The World Health Organization reports the virus has killed more than 900 people. Most of the latest deaths have occurred in Liberia.

Speaking at the State Department on Wednesday, President Obama said the U.S. and its allies will continue doing everything possible to help Liberia, Guinea and Sierra Leone respond to the crisis.
