A prosecutor also said that the man, Omar Jose Gonzalez, 42, had been arrested in Wythe County, Va., in July while carrying a sawed-off shotgun and several other firearms, as well as a map with a line pointing toward the White House. And in August, Secret Service officers saw Gonzalez near the south fence of the White House, carrying a hatchet in the back waistband of his pants. Gonzalez agreed to let the officers search his vehicle, where they found camping gear and two dogs, then released him, a prosecutor said.
