On July 8, 1955, Rushmore appeared on The Tom Duggan Show in Chicago.
He claimed on air that he was on a secret mission to uncover the communist assassins of former Secretary of Defense James Forrestal.
Rushmore told the viewers that the leader of the "Chicago Communist Party," whose name was given as "Lazarovich," was in hiding and that Rushmore needed their help in locating him.
Rushmore later disappeared from his hotel room, leading to a nationwide manhunt by the FBI.
As the nation speculated that Rushmore was either kidnapped or murdered by communists, he was discovered hiding under the name "H. Roberts" at the Hotel Finlen in Butte, Montana.
Meanwhile, news reporters found "Lazarovich" living in Manhattan under his real name of William Lazar.
Associate Director of the FBI, Clyde Tolson, wrote in the margin of a report on the disappearance: "Rushmore must be a 'nut.'
We should have nothing to do with him."
J. Edgar Hoover added in the margin: "I certainly agree."

Rushmore's second marriage was deteriorating.
In addition to Rushmore's amphetamine habit, he became an alcoholic as did his wife.
On Monday, September 5, 1955, Frances Rushmore jumped into the East River in a suicide attempt, but was rescued by an air terminal worker.
Meanwhile, Rushmore tried to get Harrison to publish a story about former First Lady Eleanor Roosevelt having an alleged affair with her African American chauffeur.
When Harrison refused, Rushmore quit.
By early February 1956, Rushmore was reportedly an editor at the National Police Gazette.

The next spring, despite Giesler's reassurances to the press, the legal effort against Confidential would go nowhere.
Since the magazine was domiciled in New York State, and the plaintiffs were California residents who initiated the suits in their own state, the suits were stopped.
On March 7, 1956, Los Angeles Supreme Court judge Leon T. David quashed Lizabeth Scott's suit on grounds that the magazine was not published in California.
Despite this setback, in addition to Scott's suit, "Giesler said he also would refile in New York a $2 million suit by actor Robert Mitchum against the magazine if it also is quashed here."
Though Giesler's initial attack failed, lawsuits from other actors continued to pile up—they would eventually total $40 million.

In September 1956, Harrison generated front-page headlines around the world when he allegedly was shot in the shoulder during a safari in the Dominican Republic by Richard Weldy, a travel agency owner and former executive for Pan American Grace Airways.
Weldy, variously described as a "jungle trapper and guide" or "a big game hunter," purportedly harbored a grudge over a Confidential story about his ex-wife, Pilar Pallete, a Peruvian actress who was then married to John Wayne.
The nonexistent Confidential article depicted Pallete as having an affair with Wayne while married to Weldy.
According to newspaper accounts, Weldy fled the scene, leaving Harrison to die alone in the jungle with his blonde girlfriend; the two were eventually rescued by the Dominican Army.
Weldy was later arrested by police.
But Harrison refused to press charges against Weldy and the two publicly reconciled.
Later the whole story was revealed to be a hoax—the shooting never took place.
Photos of a wounded Harrison in a hospital were staged.
Even the "girlfriend" was an actress that Harrison hired for the publicity stunt.
During a television interview with Mike Wallace, Harrison fooled the CBS film crew into thinking that a birthmark on his back was the bullet wound.
