"Use all our resources to trace this matter; I want to know all the operational details and the specific time they plan to act!"
After a long hesitation, Elvis still couldn't make a decision, and ultimately decided to first figure out the details of the operation before proceeding.
"Yes."
...
Three days later, in the morning.
Brod entered Elvis's office and said, "Sir, I've almost finished my investigation. The mastermind behind their action is Deputy Director Madu Aike of the FBI, and they plan to use a bomb attack for the assassination."
"What else?"
"According to the schedule, David will attend a lecture event at a local university with the Oregon State Director of the Internal Revenue Service tomorrow. According to intelligence, the assassination will take place when he returns to his hotel, where they will detonate a bomb that had been placed in his room earlier."
Listening to this, Elvis's expression became grave.
