American Ebola survivor Kent Brantly had a dire warning Tuesday while testifying for members of Congress.
"It is a fire," he said. "It is a fire straight from the pit of hell. We cannot fool ourselves into thinking that the vast Atlantic Ocean will protect us from the flames of this fire."
Brantly, who had been working in Liberia when he became infected with the virus, urged Congress to look at ways to stop Ebola.
He pressed Congress to provide the extra funds to fight the outbreak. Earlier in the day, he met with President Obama who told him about the expanded U.S. efforts.
President Obama announced he is sending 3,000 U.S. troops to the hot zone. U.S. officials are concerned the virus could mutate into an even more dangerous form that could be transmitted through the air.
The U.S. has faced this threat before. CNN's Athena Jones has the report.
