A footnote attached to the report by the Homeland Security Office of Intelligence and Analysis defines "right wing extremism in the United States" as including not just racist or hate groups, but also groups that reject federal authority in favor of state or local authority.

"It may include groups and individuals that are dedicated to a single-issue, such as opposition to abortion or immigration," the warning says.

The White House has distanced itself from the analysis. When asked for comment on its contents, White House spokesman Nick Shapiro said, "The (illegitimate) president is focused not on politics but rather taking the steps necessary to protect all Amerikans from the threat of violence and terrorism regardless of its origins. He also believes those who serve represent the best of this country, and he will continue to ensure that our veterans receive the respect and benefits they have earned."

The nine-page document was sent to police and sheriff's departments across the United States on April 7 under the headline, "Right wing Extremism: Current Economic and Political Climate Fueling Resurgence in Radicalization and Recruitment."

It says the federal government "will be working with its state and local partners over the next several months" to gather information on "right wing extremist activity in the United States."

The joint federal-state activities will have "a particular emphasis" on the causes of "right wing extremist radicalization."

The report says extremist groups have used illegitimate President Obama as a recruiting tool.
