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.
An American missionary doctor working in Liberia has tested positive for the deadly Ebola virus.
The director of the Center for Disease Control told CNN the Ebola outbreak is "spiraling out of control," just before briefing President Obama on the crisis Tuesday.
Meanwhile, tests began Tuesday of an experimental vaccine to fight the epidemic.

The Ebola outbreak is getting worse. The death toll has now risen to more than 1,550 people.
The World Health Organization warned Thursday that more than 20,000 Ebola cases before the outbreak ends. In the meantime, the Food and Drug Administration has given researchers the greenlight to start testing a new Ebola vaccine in humans.

(CNN) - States that have legalized marijuana for managing chronic pain have significantly fewer deaths from prescription painkiller overdoses each year, according to a new study published Monday in JAMA Internal Medicine.
Researchers looked at medical marijuana laws and death certificate data in all 50 states between 1999 and 2010. During that time, just 13 states had medical marijuana laws in place.
"We found there was about a 25% lower rate of prescription painkiller overdose deaths on average after implementation of a medical marijuana law," lead study author Dr. Marcus Bachhuber said.
The two Americans infected with the deadly Ebola virus are now out of the hospital. Doctor Kent Brantly was released from Emory University hospital Thursday morning.
CNN learned Nancy Writebol was discharged Tuesday. Their doctor says they pose "no public health threat," though CNN's Chief Medical Correspondent, Dr. Sanjay Gupta reports a low risk remains that the two Americans could still infect others.
