In the days before protests erupted in Los Angeles, the Trump administration stepped up its efforts to detain migrants — taking into custody those who arrived for routine check-ins while also conducting workplace raids that have sent waves of fear across Southern California and beyond.

For Vinnie Walsh, 82, of Auburn, Mass., it was “the whole nine yards — the loss of decency, courtesy, compassion, democracy.” Laurae Carpenetti, 54, a physician from the Atlanta suburbs, said that Mr. Trump’s appointment of Robert F. Kennedy Jr. as his top health official was her motivating factor.

A new poll shows a partisan split on President Donald Trump's troop deployment to quell Los Angeles protests, with 86% of Republicans supporting while Democrats strongly oppose it.

The protesters gathered in downtown L.A. are a microcosm of the Democratic coalition that has dominated the city for decades.
