Rep. James Walkinshaw has voiced strong opposition to President Trump's war policies in Iran, citing 18 American service member deaths and $37.5 billion in taxpayer funds spent without a clear strategy, while also advocating for government transparency and introducing several bipartisan bills focused on federal employees, military families, and local community needs in Fairfax.

Walkinshaw highlighted the human and financial costs of the ongoing conflict in Iran, noting that 18 American service members have been killed and Defense Secretary Pete Hegseth acknowledged $37.5 billion in taxpayer funds have been expended. He criticized the lack of a clear strategy, exit plan, or diplomatic off-ramp, and voted against a House budget framework that could allocate tens of billions more to the war. "Our service members deserve a strategy, taxpayers deserve accountability, and families deserve a Congress focused on lowering their costs," Walkinshaw said, proposing that Congress instead restore Affordable Care Act tax credits to help Americans afford health coverage.

In a push for government accountability, Walkinshaw expressed support for the "Restore Trust in Government Act," which aims to ban individual stock trading by Members of Congress, their spouses, dependent children, the President, Vice President, and Cabinet officials. He criticized a House Republican proposal for preserving loopholes, excluding the President and his family, and adding provisions that would complicate mail-in voting. "No loopholes. No carve-outs. Public service should be about serving the public, not personal profit," Walkinshaw stated.

Focusing on his constituents, Walkinshaw introduced several bipartisan legislative efforts. These include the Federal Facilities Indoor Air Quality Assessment Act to improve air quality in federal buildings, the Swatting Registry Best Practices Act to protect families and first responders from dangerous hoaxes, and the Military Installation Readiness and Resilience Act to track natural disaster costs at military bases. He also co-sponsored the Foreign Service Test-Free Reentry Act to help experienced Foreign Service Officers return to the State Department and the Capping Appointed Positions (CAP) Act to limit political appointees without Senate confirmation, aiming to protect a merit-based federal workforce.

Locally, Fairfax County was recognized with a 2026 National Association of Counties Achievement Award for its "Drone as First Responder" program, lauded for improving public safety responses. Additionally, the county is expanding its "Beyond the Bell" school-age child care program to 21 more elementary schools during the 2026–27 school year, with a full transition expected by 2029–30, aiming to reduce waitlists and provide affordable care. Walkinshaw affirmed his commitment to supporting local public safety investments and expanding child care options for working families.
