The long-awaited Senate report on torture has been released.

The lengthy document covers some of the interrogation techniques used by the CIA in the years following the 9/11 terrorist attacks and criticizes the agency for its violent techniques and mishandling of the operation.

Democratic Sen. Diane Feinstein had been pushing for the release of the Senate Select Committee on Intelligence's report on CIA enhanced interrogation techniques (EIT) since earlier this year.

On Tuesday, the summary report, almost 500 pages long, was released to the public, detailing some of the techniques used by the CIA when interrogating suspected and known terrorists. One detainee died from hypothermia after being chained naked to a concrete floor.

The report, according to USA Today, criticizes the intelligence agency for its use of waterboarding, sleep deprivation and other techniques that could be considered torture.

Because of these techniques, detainees gave agents misleading information, the report explains. For example, a detainee made an untrue confession that terrorists planned to recruit African-American Muslims from Montana.

The report also argues the CIA misled Congress, the executive branch and the American public concerning the damage of the EITs as well as their efficiency.

Furthermore, the report found the CIA employed unqualified psychologists with no knowledge of the detainees' native language or culture to conduct effective interrogations.

ABC News reports among some of the most graphic finds are those of extensive psychological and physical abuse at the hand of interrogators. Agents threatened the families of detainees with murder and rape. Other CIA agents admitted to anger issues and sexual assault.

"Numerous CIA interrogators and other CIA personnel associated with the program had either suspected or documented personal and professional problems that raised questions about their judgment and CIA employment," says the report. "This group of officers included individuals who, among other issues, had engaged in inappropriate detainee interrogations, had workplace anger management issues, and had reportedly admitted to sexual assault."

The report also finds that at least in one instance a detainees "lunch tray" was liquefied and inserted rectally.

Among those subject to EITs was al-Qaeda suspect Abu Zubaydah, who became "completely unresponsive, with bubbles rising through his open, full mouth," explains the report.

In addition, Khalid Sheikh Mohammad, mastermind of the 9/11 attacks, was subjected to a "series of near drownings."

Following the report's release, the White House released a statement in which the president expressed his displeasure with the CIA's actions.

"The report documents a troubling program involving enhanced interrogation techniques on terrorism suspects in secret facilities outside the United States, and it reinforces my long-held view that these harsh methods were not only inconsistent with our values as nation, they did not serve our broader counterterrorism efforts or our national security interests," President Barack Obama said.

Obama also pledged he would not allow the nation to "resort to those methods again."

John Brennan, director of the CIA, also released a response to the Senate's report, arguing that the CIA did what it must to protect the nation, while still admitting some things were done incorrectly. He also criticized the Senate's report, especially because it did not interview any CIA agents.
