Republican lawmakers are sounding the alarm after Minnesota Governor Tim Walz appeared to openly challenge federal authority in the wake of violent unrest following a fatal ICE shooting in Minneapolis—prompting calls for President Donald Trump to consider invoking the Insurrection Act to restore order and uphold the rule of law.

At the center of the controversy is Walz’s decision to issue a “warning order” preparing the Minnesota National Guard amid escalating tensions surrounding ICE enforcement operations. Rather than offering cooperation with federal authorities, Walz struck a defiant tone, declaring that Minnesota “does not need any further help from the federal government” and accusing the Trump administration of turning his state into a “political prop.”

To conservatives, the remarks crossed a dangerous line.

Several Republican lawmakers—among them Reps. Cory Mills, Nancy Mace, Rich McCormick, and Derrick Van Orden—warned that Walz’s rhetoric amounts to a direct challenge to federal supremacy and could even be interpreted as laying the groundwork for open conflict with federal law enforcement.

“We do not need any further help from the federal government,” Walz said, adding that the National Guard was being readied for deployment if necessary. “Minnesota will not allow our community to be used as a prop in a national political fight.”

That statement immediately raised red flags on Capitol Hill.

Rep. Rich McCormick (R-GA) didn’t mince words. “If you’re talking about bringing in military force to oppose a federal armed force, what does that sound like to the average person?” he asked. “It sounds like you want to go to war.” McCormick said Walz’s comments gave no indication of de-escalation, only provocation. “He wants to start something—and I’m being polite when I say that.”

Rep. Derrick Van Orden (R-WI) went even further, drawing a stark historical comparison. “The last time a state openly moved against the federal government was Fort Sumter—and that started the Civil War,” he said. “If a state militia acts against the federal government, that *is* civil war.”

Van Orden also blasted Walz personally, calling the governor reckless and unfit for leadership at a time when calm, cooperation, and respect for the Constitution are desperately needed.

Rep. Nancy Mace (R-SC) delivered perhaps the clearest constitutional rebuke. “Someone remind him: Donald Trump is the Commander in Chief,” she said. “Federal authority supersedes state authority. That’s not an opinion—that’s the Constitution.” Mace added bluntly, “What Walz is threatening has a name: insurrection. Mr. President, the law is on your side. Use it.”

Conservatives online echoed those concerns as the comments went viral. One widely shared post warned that Walz had suggested using the National Guard to forcibly remove federal law enforcement agents from Minnesota. “That is not protest language,” the post read. “That is a direct threat to federal authority.”

“This is a sitting governor flirting with actions that could trigger civil conflict,” the post continued. “History is clear about where this road leads—and it never ends well.”

Walz’s office declined to respond to requests for clarification.

As the Trump administration continues enforcing federal immigration law amid mounting resistance from blue-state politicians, the situation in Minnesota has become a flashpoint in a broader national struggle: whether the rule of law will prevail, or whether partisan defiance will push the country into dangerous territory. For Republicans, the answer is clear—and they’re urging the president to act before rhetoric turns into reality.
