It wasn’t the first time Trump’s ban was criticized for its effect on children. A 5-year-old boy, a U.S. citizen with an Iranian mother who flew in from Iran, was reportedly detained at Dulles International Airport for more than four hours. Spicer said those actions were necessary to keep people safe.

“To assume that just because of someone’s age and gender that they don’t pose a threat would be misguided and wrong,” Spicer said at a press conference.

Spicer gave the examples of the Boston Marathon bombers and San Bernardino shooters as reasons detaining children might be necessary. The younger of the two Boston Marathon bombers, Dzhokhar Tsarnaev, was 9 when he came into the U.S. as a refugee from Dagestan, a federal subject of Russia. San Bernardino shooter Syed Rizwan Farook was a U.S. citizen. Tashfeen Malik, the other shooter and his wife, came to the U.S. on a fiancee visa from Saudi Arabia as an adult.

Neither Russia nor Saudi Arabia are included on the list of countries from which Trump has restricted travel. Those countries are Iran, Libya, Yemen, Sudan, Somalia, Iraq and Syria.
