Kim Davis was placed in prison to force her to comply with federal law. All elected officials swear an oath to uphold the laws of the land.
Over 300 municipalities across the United States have designated themselves as "Sanctuary Cities". In doing so they violate federal law.
As chief executive, you swore an oath to uphold ALL the laws of the land, not just the ones with which you agree.
While you might not be able to deport 11 million people, you can certainly find space for 600 elected officials who are refusing to follow federal law.
Equal protection demands that these officials be treated the same way Kim Davis was treated. Please notify them immediately that failure to comply will result in this same measure, designed to bring them into compliance with federal law.
