California National Guard troops arrived in Los Angeles, escalating tensions after sporadic clashes between federal immigration agents and protesters. The deployment deepens the political rift between California and the Trump administration. President Trump's decision to mobilize nearly 2,000 guardsmen marks the first time since 1965 that a president has activated a state's National Guard without the governor's request. Many protesters said the federal deployment only escalated tensions and that the National Guard's presence was unnecessary.
