FBI Halts Cooperation With RCMP Over CBC 9/11 Terrorism Memo

The Federal Bureau of Investigation suspended cooperation with the Royal Canadian Mounted Police after a CBC report detailed a controversial terrorism memo regarding the events of September 11, 2001, according to reporting by the National Post and The New York Times.

The breakdown in intelligence-sharing highlights long-standing tensions between cross-border law enforcement agencies over sensitive security documents. According to the National Post, the freeze occurred following media coverage of internal Canadian records concerning threat assessments and counter-terrorism coordination in the wake of the 2001 attacks.

Intelligence officials from both countries have historically maintained joint operational pipelines to monitor potential cross-border security threats. The abrupt halt in bilateral communication underscores the fragility of information-sharing agreements when internal investigative memos become public, according to the New York Times reporting.

Representatives for the Royal Canadian Mounted Police and the Federal Bureau of Investigation have not announced a timeline for restoring full operational cooperation.
