When President Donald Trump put 2,000 National Guard troops under his control on Saturday night and ordered them into Los Angeles, it was billed as an urgent response to quell protests. But it was also a move long in the making.

President Donald Trump in recent days has sent thousands of National Guard troops and 700 active duty Marines to quell Los Angeles-area protests over immigration enforcement actions, despite the objections of Democratic Gov.

The president claimed, without giving evidence, that the protesters were “paid” agitators, that the Los Angeles police asked for the National Guard, and that swaths of the city were under gang control.

Detroit area police agencies said they are ready for protests that are part of a nationwide effort to oppose President Donald Trump's immigration policy.

When Immigration and Customs Enforcement agents raided worksites in Los Angeles on June 6, randomly arresting and detaining undocumented and legal immigrants, these new and invasive tactics of immigration enforcement provoked protests.

Judicial precedent backs up the federal government's authority for immigration enforcement as challenges to "sanctuary" policies loom in federal courts.

Records obtained by the Sun-Times show the police have handed over documents that include the names, addresses and countries of origin of people targeted by federal immigration authorities.

Protests over President Trump's immigration enforcement raids and his mobilization of the Marines and National Guard in Los Angeles have spread to other major U.S. cities.
