Right, except it worked under Trump. That's what happens when you let people do their jobs instead of worrying about hurting some snowflake somewhere's feelings.
https://en.wikipedia.org/wiki/Hijackers_in_the_September_11_attacks The first hijackers to arrive in the United States were Khalid al-Mihdhar and Nawaf al-Hazmi, who settled in San Diego County, California, in January 2000. They were followed by three hijacker-pilots, Mohamed Atta, Marwan al-Shehhi, and Ziad Jarrah in mid-2000 to undertake flight training in South Florida
September 11 attacks The September 11 attacks (also referred to as 9/11)[a] were a series of four coordinated terrorist attacks by the Islamic terrorist group al-Qaeda[3][4][5] against the United States on the morning of Tuesday, September 11, 2001 Who was president on September 11, 2001?
https://en.wikipedia.org/wiki/Hijackers_in_the_September_11_attacks#Before_the_attacks According to James Bamford, the NSA had picked up communications of al-Mihdhar and al-Hazmi back in 1999, but had been hampered by internal bureaucratic conflicts between itself and the CIA and did not do a full analysis of the information it passed on to the agency. For example, it only passed on the first names, Nawaf and Khalid.[20] Bamford also claims that the CIA's Alec Station (a unit assigned to bin Laden) knew that al-Mihdhar was planning to come to New York as far back as January 2000.
As you can clearly see, it was either The Deep State or The Clinton Administration or a combination of both, that allowed the attacks to be planned and carried out.
Certainly---and they told him exactly when and where. Meanwhile, years had passed while the planning was ignored.
