Senate Majority Leader Chuck Schumer is facing renewed criticism from conservatives following recent comments urging activists to “rise up” against White House policies, remarks that have drawn scrutiny amid ongoing debates over immigration enforcement and the government shutdown.

During an interview with MSNBC this week, Schumer discussed the federal budget impasse, as well as ongoing investigations into several high-profile Democratic officials, including New York Attorney General Letitia James and former National Security Advisor John Bolton. He also addressed deportation policy, a key point of contention between the Trump administration and Democratic lawmakers.

The New York senator argued that mass deportations ordered under President Donald Trump represent government overreach, saying the administration’s approach “crosses lines that shouldn’t be crossed in a democracy.” Supporters of the policy counter that deportation is a standard law-enforcement measure used by many nations to remove individuals who entered the country illegally.The exchange came as partisan divisions deepened over the continuing government shutdown. Democrats have tied the budget standoff to health-care funding, seeking to expand Affordable Care Act coverage to certain categories of migrants. Republicans have opposed that provision, saying it would incentivize illegal immigration and further strain public resources.
