President Donald Trump’s efforts to redesign federal property in Washington, D.C., face new oversight challenges following the 2026 midterm elections. With Democrats set to take control of Congress in January, lawmakers have signaled they will use their investigative and budgetary powers to review several of the administration’s projects.
The projects under scrutiny include a proposed 250-foot memorial arch at Memorial Circle, a new White House ballroom, the National Garden of American Heroes, and renovations at the East Potomac Golf Links and the Kennedy Center. These projects have been a focus for the president, who toured the ballroom site on Wednesday, Nov. 4.
Representative Jared Huffman (D-CA), the top Democrat on the Natural Resources Committee, stated in a letter to colleagues that he intends to use the committee’s authority to investigate these projects, which he characterized as "vanity projects." Representative Don Beyer (D-VA) also voiced opposition to the memorial arch during a public hearing on Thursday, Nov. 5, with a spokesperson noting that the Democratic-controlled appropriations process starting Jan. 3 will be a primary mechanism for intervention.
Legal challenges have also stalled some construction. Late Thursday, Nov. 5, U.S. District Judge Tanya Chutkan issued a 14-day stay to prevent the administration from breaking ground on the 250-foot arch. This followed an 8-4 approval vote by the National Capital Planning Commission during a 9.5-hour hearing where many witnesses expressed concern that the structure would affect the solemnity of Arlington National Cemetery. The stay allows the court to consider lawsuits filed by veterans, an architectural historian, and the governments of D.C. and Virginia.
The change in congressional leadership affects the funding and legal defense of federal construction projects in the District. For example, the Kennedy Center renovation has received $257 million in appropriations, while the seawall at the East Potomac Golf Links is estimated to cost more than $300 million. A Democratic-led Congress can investigate funding plans or use the appropriations process to check the executive branch.
The legal and legislative shifts could also affect the deployment of the National Guard in the city. Approximately 3,100 Guard members are currently stationed in D.C. following an August 2025 mobilization order. With Democrats winning governorships in Texas, Georgia, Iowa, and Nevada on Nov. 3, these new state executives may choose to withdraw the more than 600 troops their states currently provide.
The shift in House leadership also changes how the chamber interacts with the judicial branch. The next Speaker of the House will appoint a new general counsel for the House. According to a spokesperson for Rep. Beyer, this will allow the House majority to pull back the balance of power and participate in litigation without ceding the standing they lacked while in the minority. The next major milestone occurs on Jan. 3, 2027, when the new Congress is seated.
