Oregon House Advances Bill Limiting Federal National Guard Deployments — With Implications for Southwest Washington

Oregon lawmakers have approved a measure intended to restrict a president’s ability to deploy National Guard troops from other states into Oregon without the governor’s consent. The proposal, House Bill 4091, passed the Oregon House on Thursday and now heads to the state Senate for consideration.

According to reporting by Oregon Public Broadcasting, the bill is a direct response to federal actions in 2025, when President Donald Trump attempted to deploy National Guard units from multiple states — including Oregon — to Portland for law enforcement and immigration enforcement purposes. That effort collapsed after U.S. District Court Judge Karin J. Immergut ruled that the deployment violated the U.S. Constitution, a decision detailed in her November 2025 ruling covered by OPB.

On the Oregon House floor, Rep. Paul Evans, a Democrat from Monmouth and the bill’s chief sponsor, acknowledged that HB 4091 may not improve relations between Oregon and federal leadership. But, he argued, the measure clarifies the National Guard’s intended role and protects state-level readiness for emergencies such as wildfires and seismic events.

Rep. Daniel Nguyễn, a Democrat representing a district that includes Oregon’s only ICE facility, described the impact of past federal deployments on his community, noting that constituents saw National Guard helicopters overhead for weeks during heightened immigration-related enforcement. “I can tell you that it did not look like a war zone until our commander in chief ordered it to be a war zone,” Nguyễn said during floor debate.

Opposition came primarily from Republican legislators, including Rep. Alek Skarlatos of Canyonville, who argued the bill is unlikely to change federal behavior and may invite legal challenges. Skarlatos, a former Oregon National Guard member, warned the measure could negatively affect the Guard’s public reputation.

Evans ran a similar bill in 2025, which cleared the House but failed in the Senate. This year’s version returns amid continued legal disputes nationally over the limits of federal power in deploying state-controlled Guard units.

Though centered in Oregon, HB 4091 carries implications for Southwest Washington. Cowlitz County residents live directly across the Columbia River from Portland, where federal deployment decisions have had visible regional impact in recent years. Any policy altering how National Guard forces may be introduced into the Portland metropolitan area has indirect consequences for cross-border emergency planning, transportation stability, and the regional security environment.

HB 4091 will next be scheduled for hearings and debate in the Oregon Senate. The timeline for a final vote is not yet publicly available.

Why this matters for Southwest Washington

The Portland metropolitan area functions as an interconnected regional ecosystem. When National Guard deployments escalate in Portland, the effects often ripple north into Clark and Cowlitz counties — from traffic disruptions on I‑5 and I‑205 to elevated law enforcement coordination across state lines. Clarifying the limits of federal deployment authority in Oregon shapes how regional emergency managers and local governments in Southwest Washington anticipate and respond to future high‑intensity events in Portland’s urban core.
