WASHINGTON (AP) - Vice President Joe Biden is arguing that there would be no practical benefit in shutting down the country's border with Mexico.
And the acting head of the Centers for Disease Control and Prevention, Dr. Richard Besser, agreed with the administration's sentiment Thursday, saying there could be "negative consequences" to this option for containing the spreading swine flu virus.
Interviewed on CBS's "The Early Show," Biden called closing the border "a monumental undertaking" and said it would involve far more complications than simply shutting down schools or postponing public meetings.
Besser said on ABC's "Good Morning America" there would be "no added value" of a border closing. He also said U.S. public officials would be wary of using thermal sensors to detect people who are sick, saying that wouldn't be very effective in this case "where you are able to transmit the day before you have symptoms."
