Jeh Johnson on Inauguration: We Must Be Concerned About Lone Wolves, Vehicle Threats

EXCERPT:

SCARBOROUGH: "What's your greatest concern?"
JOHNSON: "Well, I said last week that we see no specific credible threat directed against the inauguration, but that's only part of the story."
SCARBOROUGH: "Right."
JOHNSON: "We live in an age now of the self-radicalized actor, the so-called lone wolf, and we have to be concerned about the vehicle threat, [like] in Nice, for example."
