O’Reilly on Ebola Threat: ‘Obama Should Order an Immigration Quarantine’

We learned this morning that an NBC News cameraman was diagnosed with the virus and will head back to the United States for treatment.

On Fox and Friends today, CDC Director Tom Frieden pushed back, saying sealing borders and preventing travel is not the best way to handle this situation.

Martha MacCallum discussed that with Guy Benson and Julie Roginsky, questioning how schools in the Dallas area have handled this threat.

Many parents expressed concern after reports that five schoolchildren had been in contact with Thomas Duncan, the first person to be diagnosed with Ebola in the U.S.

Officials maintained the threat to children was very low and schools remained open.

Martha asked why officials would not "err on the side of caution" and close some schools.

"It boggles my mind when you consider that school across this country, many of them close when there are two snowflakes in the sky," she said, pointing out that when it snows there's panic and "everything literally shuts down."

She argued that officials could easily make up the days later and send homework home out of an abundance of caution.

Benson believes officials are being careful not to fuel panic and fear about Ebola if they don't have to. Roginsky agreed with MacCallum, saying as a mom she wouldn't be sending her child to that school in Dallas.
