Since the September 11 attacks on the United States and the subsequent implementation of the Patriot Act , which was overwhelmingly passed by Congress and signed into law and strongly supported by President George W. Bush , some Communist groups in the United States have been subjected to renewed scrutiny by the government . On 24 September 2010 , over 70 FBI agents simultaneously raided homes and served subpoenas to prominent antiwar and international solidarity activists who were thought to be members of the Freedom Road Socialist Organization ( FRSO ) in Minneapolis , Chicago and Grand Rapids and they also visited and attempted to question activists in Milwaukee , Durham and San Jose . The search warrants and subpoenas indicated that the FBI was looking for evidence that was related to their " material support of terrorism " . In the process of raiding an activist 's home , FBI agents accidentally left behind a file of secret FBI documents which showed that the raids were aimed at people who were actual or suspected members of the FRSO . The documents revealed a series of questions that agents would ask activists regarding their involvement in the FRSO and their international solidarity work that was related to their dealings with the Colombia and the Palestine . Later , members of the newly formed Committee to Stop FBI Repression held a press conference in Minnesota in which they revealed that the FBI had placed an informant inside the FRSO in order to gather information prior to the raids
