 The Bureau finished their search on Monday after combing through the residence where the 20-year-old who shot former President Donald Trump and three others at a rally on Saturday lived. The Secret Service fatally shot Crooks within seconds of his opening fire on the former president, whose ear was grazed by a bullet and hit three other people, one of whom died. Donald Trump is making his first public appearance since being injured in that assassination attempt on Saturday. More from Mark Mayfield.
