It has become increasingly clear that former President Donald Trump's haters don't just want him to lose elections or be criminally convicted but instead are determined to see him dead.

It was just revealed that an Idaho man was arrested last month and charged with threatening to kill Trump after he made nine threatening calls in one day to the former president's Mar-a-Lago residence in South Florida, according to the Daily Mail.

Warren Jones Crazybull, 64, of Sandpoint, Idaho, was arrested in Montana on August 1, criminally indicted in a federal court on August 20, and is scheduled to next appear in court on October 28. He pleaded not guilty to a single count of making threats against a former president.

Arrested over numerous threats against Trump

On July 31, just a few weeks after a would-be assassin nearly killed former President Trump at a campaign rally in Pennsylvania, Crazybull allegedly made at least nine separate calls to Trump's Mar-a-Lago residence that included threats to find and kill the former president.

The Mar-a-Lago security team informed the U.S. Secret Service about the threatening calls and that the man's identity was revealed by caller ID, which was subsequently confirmed by the Secret Service through phone records and a comparison of his voice with videos posted to his since-deleted social media accounts.

Once positively identified, Crazybull was then tracked down by federal agents using the location data of his cellphone and was taken into custody in Montana.

Allegedly upset over loss of tribal land

According to eastern Washington state's The Spokesman-Review, Crazybull, who claims to be a member of the Rosebud Sioux Tribe in South Dakota, was reportedly motivated to threaten to kill the former president over the alleged loss of tribal lands.

Specifically, Crazybull reportedly blamed Trump and others for violating prior treaties by authorizing the construction of the Keystone XL oil pipeline, which the tribe unsuccessfully sued to block because it crosses tribal lands and the tribe was not consulted before it was built.

The outlet noted that when he was arrested in Montana, he insisted that he didn't really pose a threat to the former president, that he had no firearms or special training, that he'd been admitted to receive psychiatric care in the past, and that his threats were merely intended to draw attention to his concerns.

If convicted, Crazybull could be sentenced to serve up to five years in federal prison.

"Hateful rhetoric" from Democrats is to blame for attempts on Trump's life

Unsurprisingly, former President Donald Trump and his campaign were not happy about the news of yet more threats against his life, which they attributed to the increasingly dire and violent rhetoric employed against him by his political opponents in the Democratic Party and the media.

"Kamala Harris and liberal Democrats are the ones who are deranged," Trump campaign spokesman Steven Cheung said Monday, according to NBC News. "There have been two heinous assassination attempts on President Trump, and their violent rhetoric are directly to blame."

"If the Democrats and Kamala Harris do not come out and apologize for their hateful rhetoric and tone down their attacks that have stoked the flames of violence, they are explicitly advocating for and inciting more bloodshed against President Trump," he added.

Unfortunately, given how that rhetoric has not been toned down following at least two recent assassination attempts against Trump -- that we know of -- it seems likely that others incited by the dangerous anti-Trump hyperbole of Democrats and the media will feel emboldened to take a chance at trying to kill him.
