Mike Lackomar of Michigan-Militia.com said he heard from other militia members that the FBI targeted the Hutaree after its members made threats against Islamic organizations.
Although there had been reports the Hutaree may have targeted Muslims, there is no mention in the indictment of any threats against them.
The Council on American-Islamic Relations issued a statement Sunday asking federal law enforcement officials to release more information about possible threats against Muslims.
"Given the recent sharp spike CAIR offices nationwide have observed in anti-Islam rhetoric, it would not be surprising that an extremist group would seek to turn that bigoted rhetoric into violent actions," said Nihad Awad, CAIR national executive director in Washington.
Government Intercedes on CAIR's behalf.
