AZ Gov. Brewer Vetoes Unconstitutional Bill Tied To Radical ‘Oath Keepers’ | The Arizona legislature recently passed an unconstitutional bill that generally requires federal law enforcement officials to notify county sheriffs such as Joe Arpaio before they take action within the state. The lead sponsor of the bill, Rep. David Gowan (R) is tied to the “Oath Keepers,” a far right law enforcement group that encourages law enforcement to defy federal “orders” the Oath Keepers believe are unconstitutional. To her credit, Gov. Jan Brewer (R) vetoed this bill on Wednesday.
