Malia, 13, was reportedly on a school trip to the Mexican state of Oaxaca when the earthquake hit. The U.S. Geological Survey says the earthquake was felt in the area.
This marks a rare instance where the White House finds it necessary to discuss the Obama children, who are usually only mentioned when they are with the President or First Lady.
Republican presidential candidate Rick Santorum voiced his disapproval of the decision to allow Malia to travel south of the border, saying that a State Department travel warning had been issued for the country.
"If the administration is saying that it's not safe to have people down there, then just because [the President] can send 25 Secret Service agents doesn't mean [he] should do it," Santorum told radio talk show host Glenn Beck. "And when the government is saying this is not safe, then you don't set the example by sending your kids down there."
