Long lines at major U.S. airports 'unacceptable,' U.S. fixing problem - official

WASHINGTON, March 15 (Reuters) - Long lines and delays at U.S. international airports for returning U.S. travelers being screened for coronavirus are "unacceptable" and the government has made adjustments to fix the problem, a senior U.S. official said on Sunday.

Acting Homeland Secretary Chad Wolf spoke at a White House news conference on a day when television stations showed travelers crowded close together in airport lines at Chicago's O'Hare and other major airports after President Donald Trump imposed restrictions last week on travelers from Europe.
