Melania Trump calls for investigation into Trump assassination attempt: "It's time to reveal the facts"

• In a new social media video post, Melania Trump, the former first lady, questioned the authenticity of the attempted assassination of her husband, Donald Trump, the Republican presidential nominee.
• Melania Trump's post on X advertised the launch of her new memoir, "Melania."
• At a campaign rally in Pennsylvania in July, Thomas Crooks, who had fired at Donald Trump and others, was killed by the Secret Service.

This summer, the attempted assassination of Republican presidential nominee Donald Trump was questioned by Melania Trump, the former first lady.

In a 30-second video posted on social media, Trump claims that there is "more to the story" and argues that his new memoir provides a different perspective.

The failure of law enforcement to apprehend Thomas Crooks prior to the near-fatal shooting of Donald Trump at a rally in western Pennsylvania is the specific concern she raises.

"The experience of attempting to end my husband's life was horrific and distressing," she says on the video. "The silence surrounding it now feels oppressive."

"I can't help but wonder, why didn't law enforcement officials arrest the shooter before the speech?" she said. "There is definitely more to this story, and we need to uncover the truth."

An image of her new book, "Melania," is shown at the end of the video, along with a link to purchase copies. The book will be available for purchase the second week of October.

The campaign of Donald Trump was contacted by CNBC to request a comment on the statement made by his wife online prior to the scheduled debate with Vice President Kamala Harris in Philadelphia.

The Secret Service has been heavily criticized for its inability to prevent Crooks from shooting during a rally in Butler Township, Pennsylvania, on July 13. Crooks had positioned himself on a roof overlooking the rally site.

Corey Comperatore, a former fire chief, was killed by gunfire while Trump's ear was hit. Several others were injured before Crooks was fatally shot by the Secret Service.

Police identified Crooks as suspicious near the rally because he was milling about and stood out to them due to not entering the venue through a designated point of ingress, according to Pennsylvania State Police Col. Christopher Paris at a House Homeland Security Committee hearing on July 23.

Crooks was later spotted by police carrying a range-finder, according to Paris.

A Butler Township police officer was shot by a gun-wielding Crook after he climbed onto the roof of a building.

On July 23, Kimberly Cheatle, the Secret Service's director at the time of the shooting, resigned after being criticized by members of a House of Representatives committee for her handling of the shooting.
