President Barack Obama met with Nina Pham on Friday after the Dallas, Texas, nurse was released from the National Institutes of Health's (NIH) Clinical Center in Bethesda, Maryland. Pham and a second nurse, Amber Vinson, were treating a patient, a Liberian man who later died from the disease, when they contracted the virus at Texas Presbyterian Hospital. White House spokesman Josh Earnest said Obama met Pham in the Oval Office to thank her for doing her job at the Dallas hospital. "She was doing the work that many nurses do on a daily basis and she did so even though it did put her at some risk," Earnest told reporters. Earnest said that Pham had been tested five times before she was released from the NIH hospital. Vinson was transferred to Emory University Hospital in Atlanta, Georgia, after she was infected with Ebola, and the hospital said Friday that tests indicate that the virus is no longer in her blood. Vinson has not been released from the Atlanta hospital yet.
