 The existence of the intelligence threat from a hostile foreign intelligence agency and the enhanced security for Trump raises new questions about the security lapses at the Saturday rally in Butler, Pennsylvania, and how a 20-year-old man managed to access a nearby rooftop to fire shots that injured the former president. A U.S. national security official said the Secret Service and Trump campaign were made aware of the threat before Saturday's rally. Secret Service learned of the increased threat from this threat stream, the official told CNN.
