Rep. Mario Diaz-Balart

Representative for Florida’s 25th District

pronounced MAH-ree-oh // DI-az buh-LAHRT


Diaz-Balart is the representative for Florida’s 25th congressional district (view map) and is a Republican. He has served since Jan 3, 2013. Diaz-Balart is next up for reelection in 2022 and serves until Jan 3, 2023.

He was previously the representative for Florida’s 21st congressional district as a Republican from 2011 to 2012; and the representative for Florida’s 25th congressional district as a Republican from 2003 to 2010.

Diaz-Balart is among the Republican legislators who, by calling for entire states to be disenfranchised in the 2020 presidential election, fomented the terrorist attack on the Capitol on January 6, 2021 that aimed to prevent the determination of the next president of the United States. Shortly after the 2020 election, Diaz-Balart joined a case before the Supreme Court calling for all the votes for president in Georgia, Michigan, Pennsylvania, and Wisconsin — states that were narrowly won by Democrats — to be discounted, claiming that some voters there followed procedures set by the wrong state officials. The case amplified lies and conspiracy theories that fueled the movement that led to the attack on the Capitol. The Supreme Court rejected the case. Following the rejection of several cases before the Supreme Court, one legislator called for violence. On January 6, 2021 in the hours after the attack on the Capitol, Diaz-Balart voted for the exclusion of Arizona and/or Pennsylvania — states narrowly won by Democrats — from the count of Electoral College votes that determined the next President of the United States.

Does 3 not sound like a lot? Very few bills are ever enacted — most legislators sponsor only a handful that are signed into law. But there are other legislative activities that we don’t track that are also important, including offering amendments, committee work and oversight of the other branches, and constituent services.

We consider a bill enacted if one of the following is true: a) it is enacted itself, b) it has a companion bill in the other chamber (as identified by Congress) which was enacted, or c) if at least about half of its provisions were incorporated into bills that were enacted (as determined by an automated text analysis, applicable beginning with bills in the 110th Congress).
