DAVID MUIR: We also have new reporting tonight on the alleged assassination attempt of then-candidate Donald Trump. What the president at the president's Florida golf course on that day allegedly tried to get his hands on before that day, including anti-aircraft weapons. Here's Pierre Thomas.
PIERRE THOMAS: Tonight, months after his dramatic arrest, federal prosecutors releasing disturbing new details which they claim show Ryan Routh’s apparent obsession with assassinating President Trump. Before he allegedly stalked Trump on his Florida golf course, prosecutors say Routh, a fierce supporter of Ukraine, who had visited the war-torn country multiple times, reached out to an associate there. His request: “send me an RPG (rocket-propelled grenade) or Stinger surface-to-air missile. Prosecutors claim Routh desperately wanted to blow up then-candidate Trump's plane writing: “I need equipment so that Trump cannot get elected.”
DONALD TRUMP: Take a look at what happened… (GUNFIRE)
THOMAS: The second assassination attempt coming just two months after Trump was nearly killed in Pennsylvania. Authorities in Florida say Routh waited for 12 hours in a sniper's nest just off Trump's golf course. A Secret Service agent positioned one hole ahead of the president spotting the barrel of an assault rifle in the bushes, engaging the suspect before he could take a shot at Trump. And now, the FBI says Routh could have had an even more powerful weapon, after he first tried to buy a .50 caliber rifle, capable of piercing body armor and slicing through car doors. Routh has pleaded not guilty, but the FBI says they have footage of him conducting surveillance and placing him at the scene just before the alleged attempt. David.
MUIR: All right. Pierre Thomas in Washington tonight. Pierre, thank you.
