 I want to follow up with the latest information that you have, that they found explosive materials in the car. We also know that they're doing a search of the gunman's home, but all that potentially points to trying to do something even larger than just taking aim at the former president. How is security being ramped up at other high-profile locations? We know that New York City stepped up security at Trump Tower, other landmarks here around the city, and the RNC is just around the corner in Milwaukee.
