At a White House event,President Barack Obama scolded politicians who have
sought quarantines or strict travel bans for caving into fears,although he did
not mention anyone by name.
"When I hear people talking about American leadership,and then are promoting
policies that would avoid leadership and have us running in the opposite
direction and hiding under the covers,it makes me a little frustrated," Obama
said.
