Considering everything that’s happening in America at the moment, the Obama Justice Department consistently displays their own particular brand of priorities:

From the Washington Examiner:

The Denver Sheriff Department will accept a penalty from the Department of Justice after a federal probe found it wrongly made U.S. citizenship a job requirement during a recent hiring spree.

The sheriff’s department — the biggest sheriff’s office in Colorado — will pay a $10,000 fine after it required applications for deputy sheriff jobs to be U.S. citizens when hiring from the beginning of 2015 through March 2016. The department went on a hiring spree of 200 deputies as part of its ongoing reform.

The Justice Department made the announcement on Monday, saying the sheriff’s department violated the Immigration and Nationality Act without having an exemption.

It’s possible the Obama DOJ was extra sensitive about the sheriff’s department’s oversight considering it took place in a sanctuary city.

Maybe just a little.
