Current office and congressional role
Mario Díaz-Balart represents Florida’s 26th Congressional District in the U.S. House of Representatives. A Republican, he first entered Congress on January 3, 2003, after serving in both chambers of the Florida Legislature. The current House directory identifies the 26th District as his seat, while his official biography describes communities in Miami-Dade and Collier counties within the district. His current role should not be confused with an older district number from an earlier map. S1 S2 S3
His congressional career has included extensive appropriations work. The present biography identifies him as vice chair of the House Appropriations Committee and chair of its National Security, Department of State, and Related Programs Subcommittee. These assignments are a useful starting point for understanding his current responsibilities, not a guarantee of funding for a particular local project. S3
Early life, education and Florida roots
Díaz-Balart was born in Fort Lauderdale on September 25, 1961, and graduated from Miami Shores Preparatory High School in 1979. The House historical directory records attendance at the University of South Florida. His official biography identifies political science as his field of study. Neither source is treated here as evidence of an earned bachelor’s degree when the directory records attendance rather than graduation. S1 S3
The historical record also identifies him as the brother of former Representative Lincoln Díaz-Balart and describes work as a marketing executive. Those public facts help distinguish him from similarly named family members without making family association a substitute for his own record. The relevant Florida connection is both personal and professional: birth in Broward County, education in the state and elected service spanning Tallahassee and Washington. S1
Service in the Florida Legislature
The House historian records two periods in the Florida House, from 1988 to 1992 and from 2000 to 2002, with Florida Senate service between 1992 and 2000. That chronology matters because it was not one uninterrupted House tenure. His official biography describes committee leadership in the state Legislature, including appropriations responsibilities, before his election to Congress. S1 S3
The move to federal office followed election in 2002, with congressional service beginning in January 2003. A person page can preserve that first-service date while a seat page separately records the current term. This avoids confusing a long-serving representative’s original entry into Congress with the oath at the start of the 119th Congress in January 2025. S1 S2
What the appropriations portfolio involves
Appropriations is the congressional process for providing funding through legislation. Díaz-Balart’s present subcommittee portfolio concerns national security, the Department of State and related programs. His biography also lists membership on the Defense Subcommittee. The historical House record shows earlier leadership of the Transportation, Housing and Urban Development appropriations subcommittee and, in the 118th Congress, the State, Foreign Operations and Related Programs subcommittee.

These are related but not identical assignments. The historical titles should remain attached to the Congresses in which they applied. The current committee and official assignment pages should govern a reader’s description of his present work. Changing a subcommittee’s name or jurisdiction is not evidence that a member’s entire earlier record has disappeared. S4
For residents, the practical value of this information is knowing where to look next. A proposed appropriation may appear in a request, a committee bill, a floor vote and a final law at different times. A local announcement about an award is another kind of record. None should be silently substituted for the others when describing results.
Florida issues and public-record examples
His official materials identify the Everglades Caucus as an area of work. They also describe district communities that include both urban Miami-Dade neighborhoods and communities in Collier County. That mix helps explain why transportation, water and federal spending recur in his public portfolio, alongside international affairs. It does not establish that every constituent or locality shares his policy positions. S4
A current office announcement concerning the Collier County Sheriff’s Office describes a $2,504,543 equipment-related funding presentation. The announcement is evidence of what the office reported, not an independent audit of procurement or delivery. A publication should retain the project’s specific recipient and purpose rather than convert the figure into money paid directly to every resident. S5
Díaz-Balart also hosted a Service Academy Day on September 19, 2026. The office described it as the nineteenth annual event and identified participation connected with the federal service academies. This is a practical constituent-service activity: students and families can learn about application pathways, nominations and military education. It is not a promise that attending an information session produces an appointment. S6
That example illustrates why a biography should include more than a list of bills. Congressional offices also provide public information and help residents understand federal processes. These activities are part of the office’s work even when they do not result in a new statute. Their dates should remain explicit so an old event is not presented as a future appointment.
Public contact and evaluating the record
The House Clerk lists the Washington office at 374 Cannon House Office Building, Washington, DC 20515, with telephone 202-225-4211. The official website provides district information, services and contact options. A resident seeking assistance should confirm the current district and use the office’s designated process rather than rely on a campaign directory or an old address. S2
A neutral reading of Díaz-Balart’s record separates his Florida legislative career, current appropriations authority, reported district projects and constituent services. The sources linked here allow readers to check each category. His party affiliation is a factual roster field; the biography neither endorses his positions nor assumes that a senior committee role resolves the merits of any particular funding or foreign-policy decision.
