Melania Trump suggests conspiracy theory about husband's assassination attempt

Melania Trump spread conspiracy theories around the apparent assassination attempt against her husband as she promoted her forthcoming memoir.

The former first lady has been releasing video clips on social media to promote the book, "Melania," which will be released by Skyhorse Publishing on Oct. 8. In a 34-second clip published Tuesday morning, she questioned the response by law enforcement to a gunman who fired shots at Donald Trump at a rally in Butler, Pennsylvania.

"The attempt on my husband's life was a horrible, distressing experience," Trump says in the video. "Now the silence around it feels heavy. I can't help but wonder, why didn't law enforcement officials arrest the shooter before the speech? There is definitely more to the story, and we need to uncover the truth."

The video then shows an image of her self-titled book, although it's not clear if its contents touch on the July 13 shooting, and invites viewers to order a copy online.

"Writing this memoir has been a deeply personal and reflective journey to me," she said in a previous video. "As a private person who has often been the subject of public scrutiny and misrepresentation, I feel a responsibility to clarify the facts.

A House bipartisan task force is investigating the shooting that left a Trump supporter dead and the former president with a gunshot wound to his right ear, and lawmakers are focusing on communication problems between the Secret Service and law enforcement that allowed 20-year-old Thomas Crooks to climb onto the roof of a building and fire off shots.

A Secret Service sniper fatally shot the gunman, but not until he had already killed former fire chief Corey Comperatore, injured Trump and wounded two other supporters at the rally.
