Liberia's head of state called the mayor of Dallas to extend a personal apology for her country's role in transmitting the deadly Ebola strain to the U.S., but the Texan absolved her of any responsibility, according to a report.

The Guardian reported that Liberian President Ellen Johnson Sirleaf told Dallas mayor Mike Rawlings that she felt accountable for the disease, transferred to U.S. shores by Liberian national Thomas Eric Duncan.
