President Barack Obama on Friday turned to a trusted adviser to lead the nation’s Ebola response as efforts to clamp down on any possible route of infection from three Texas cases expanded, reaching a cruise ship at sea and multiple airline flights.

Facing renewed criticism of his handling of the Ebola risk, Obama will make Ron Klain, a former chief of staff to Vice President Joe Biden, his point man on fighting Ebola at home and in West Africa. Klain will report to national security adviser Susan Rice and to homeland security adviser Lisa Monaco, the White House said.
