President Barack Obama is naming Ron Klain, a former chief of staff to Vice President Joe Biden and a trusted adviser at the Obama White House, as the point man on the U.S. government's response to the Ebola crisis.
Obama has been under pressure to name an Ebola "czar" to oversee health security in the U.S. and actions to help stem the outbreak in West Africa.
Klain has been out of government since leaving Biden's office during the Obama's first term. The White House said that Klain would report to national security adviser Susan Rice and to homeland security and counterterrorism adviser Lisa Monaco.
Klain, a lawyer, also served as chief of staff for Vice President Al Gore. He previously served under Attorney General Janet Reno in the Clinton administration.
But he says imposing a travel ban from disease-ravaged West Africa, as Republicans have demanded, would be counterproductive.
Texas toughens monitoring
In Dallas, the epicenter of Ebola in the U.S., officials took a tougher approach toward monitoring dozens of health care workers who were exposed to the virus while treating an infected patient who later died. The health care workers were asked to sign legally binding documents agreeing not to go to public places or use public transportation.
Those who break the agreement could face undisclosed sanctions.
The move came after two nurses who had treated Thomas Eric Duncan at Texas Health Presbyterian Hospital were diagnosed with Ebola and the disclosure that one of them had flown roundtrip between the Dallas area and Cleveland before her diagnosis.
Self-monitoring was extended Thursday to people who took the same outbound flight as nurse Amber Vinson; it had been imposed earlier for passengers on the return trip. Another group being contacted: shoppers at the Akron bridal shop Vinson visited that Saturday.
Both nurses have been transferred from the Texas hospital where they treated Duncan and became infected. Nina Pham was transferred on Thursday to the National Institutes of Health in Bethesda, Maryland, and Vinson on Wednesday to Emory University Hospital in Atlanta. The two facilities are among four in the United States that have specialized isolation units.
A video released by Texas Health Presbyterian Hospital showed Pham in her hospital isolation ward before her transfer, speaking to her physician, Dr. Gary Weinstein. At one point Pham begins crying, and Weinstein, dressed in full personal protection gear hands her a tissue. "I love you guys," she says. "We love you, Nina," responds Weinstein.
The two nurses have been the only cases of transmission in the U.S. Duncan was exposed to the virus in Liberia and was diagnosed after traveling to Texas.
Government officials said early Friday that a Dallas health care worker who handled a lab specimen from Duncan is on a Caribbean cruise ship where she has self-quarantined and is being monitored for any signs of infection. State Department spokeswoman Jen Psaki said in a statement that the woman had shown no signs of the disease.
The government is working to return the woman and her husband to the U.S. before the ship completes its cruise. When the woman left the U.S. on the cruise health officials were requiring only self-monitoring, Psaki said.
The magnitude of the Ebola outbreak continues to grow in Africa; the World Health Organization forecast the death toll would surpass 4,500 by the end of the week.
In Geneva, the U.N. high commissioner for human rights, Zeid Raad al-Hussein, paired the Ebola outbreak and the Islamic State group as "twin plagues" that will cost the world many billions of dollars to overcome, and the United Nations made an urgent appeal for more money to fight the disease.
Canceling a campaign fundraising trip for the second straight day, Obama met into the evening with top aides and health officials. The White House said Obama also placed calls to Canadian Prime Minister Stephen Harper and Swedish Prime Minister Stefan Lofven to discuss the need for an international response to the outbreak in West Africa.
Obama authorized a call-up of reserve and National Guard troops in case they are needed. His executive order would allow more forces than the up-to-4,000 already planned to be sent to West Africa, and allow for longer periods of time. Speaking to reporters at the White House, Obama said several people leading the government's Ebola response also have other priorities.
"It may make sense for us to have one person ... so that after this initial surge of activity we can have a more regular process just to make sure we are crossing all the T's and dotting all the I's," he said.
He said he had no "philosophical objection" to imposing a travel ban on West Africa if it would keep Americans safe but had been told by health and security experts that it would be less effective than measures already in place.
Earlier in the day, during a contentious congressional hearing, Republican after Republican demanded that Obama impose a travel ban.
When federal health officials stressed the importance of stopping the outbreak at its source, Rep. Fred Upton, R-Mich., responded, "You're right, it needs to be solved in Africa. But until it is, we should not be allowing these folks in, period."
"People's lives are at stake, and the response so far has been unacceptable," declared Upton, chairman of the Energy and Commerce Committee. A handful of congressional Democrats also have endorsed the travel ban that's mainly been pushed by Republicans.
About 100 to 150 people fly into the U.S. each day from Liberia, Sierra Leone and Guinea, the three nations hit hardest by Ebola.
Rep. Tim Murphy, R-Pa., said the "American public loses confidence each day" - a result of the failure to protect the two nurses and other mistakes.
Dr. Tom Frieden, director of the Centers for Disease Control and Prevention, told lawmakers that the investigation into how the nurses became infected with Ebola was ongoing.
