Deep-cut case law and 19th century constitutional interpretation underpin the Trump administration argument for deploying troops to Los Angeles.

WASHINGTON, June 12 (Reuters) - Americans are divided over President Donald Trump 's decision to activate the military to respond to protests against his crackdown on migrants, with about half supportive of the move, according to a Reuters/Ipsos poll that closed on Thursday.

Protests against immigration officers are spreading beyond Los Angeles. Trump’s immigrant crackdown now includes ICE workplace quotas. Republicans are increasingly split over the deficit impact of Trump’s bill.

With migrant communities already living in fear amid the Trump administration's immigration crackdown, ICE raids in downtown Los Angeles sparked days of protests.

President Donald Trump's eventful week included securing a preliminary trade deal with China, deploying National Guard troops to Los Angeles, and responding to Israel's strikes on Iran.

Hundreds of people gathered at Washington Square Park in downtown City on Thursday, protesting the Trump administrations's raids on undocumented immigrants. Then they marched to the federal building.

The protest comes before leaders vote on whether or not to pass a budget that is expected to lock new undocumented immigrants out of Medi-Cal.

A Chicago protest is planned for Thursday afternoon by immigration advocates, who are calling for ICE tactical teams sent by the Trump Administration to stand down.
