A curious toddler on Tuesday earned the title of one of the tiniest White House intruders after he squeezed through the metal fencing on the north side of the executive mansion, causing a brief interruption to access while Secret Service officers retrieved him and reunited him with his parents. The officers briefly questioned the parents before allowing them to continue on their way. Secret Service spokesman Anthony Guglielmi said that the toddler “briefly entered White House grounds” and that the security system had triggered an immediate response from officers.
