Revealed: FBI violated its own rules while spying on Keystone XL opponents

The FBI breached its own internal rules when it spied on campaigners against theKeystone XL pipeline, failing to get approval before it cultivated informants and opened files on individuals protesting against the construction of the pipeline in Texas, documents reveal.

Internal agency documents show for the first time how FBI agents have been closely monitoring anti-Keystone activists, in violation of guidelines designed to prevent the agency from becoming unduly involved in sensitive political issues.

The hugely contentious Keystone XL pipeline, which is awaiting approval from the Obama administration, would transport tar sands oil from Canada to the Texas Gulf coast.

It has been strongly opposed for years by a coalition of environmental groups, including some involved in nonviolent civil disobedience who have been monitored by federal law enforcement agencies.
