Trump Threatens to Invoke Insurrection Act as Minneapolis Protests Escalate. US President Donald Trump has warned he could invoke the rarely used Insurrection Act to crack down on unrest in Minneapolis tied to federal immigration enforcement. The threat came after a night of protests and vandalism following a shooting involving a federal agent. The Department of Homeland Security says the officer opened fire after being attacked by three Venezuelan nationals with a shovel and a broom handle, striking one man in the leg. All three suspects were arrested, and the agent was taken to hospital. Tensions in the city have been high since an immigration agent fatally shot 37-year-old Renee Nicole Good earlier this month, an incident now under FBI investigation. The Trump administration says the agent acted in self-defence, while local officials dispute that account. As clashes continued, Trump said he would deploy troops if state leaders failed to restore order, accusing protesters of being "professional agitators.”
