On Wednesday, President Obama held an emergency meeting with key cabinet agencies coordinating the federal government response.

After the meeting, the president told reporters that those in charge of responding to the health emergency must attack it "in a much more aggressive way" and promised that there would be an answer to the question of how supposedly protected nurses became sickened themselves when treating Dallas Ebola-infected patient Thomas Eric Duncan, who later died.

Obama said that Americans should have faith in the government's handling of the crisis. He also claimed that Ebola does not pose any significant health threat to most of the public.
