Rep. Brian Mast, who represents Florida’s 21st district in the U.S. Congress, posted a series of updates on July 27, 2025, addressing infrastructure improvements for the Coast Guard, health risks from toxic algae in Lake Okeechobee, and hurricane preparedness.
In a tweet at 11:53 a.m., Mast highlighted legislative efforts to support maritime safety: “We’re fixing aging infrastructure, investing in new technologies, and making sure our Coast Guard has the tools they need to keep our waters—and our nation—safe. Here more about the Coast Guard Authorization Act of 2025 we passed in the House this week: https://t.co/dA2JRPPGyp” (July 27, 2025).
Later that day at 5:03 p.m., Mast warned residents about environmental hazards affecting local waterways: “Toxic blue-green algae is at dangerously high levels in Lake O. Do not go in the water, don’t let your pets go in the water. These health risks are real. Hear more about the issue below: https://t.co/gekPQpak4E” (July 27, 2025).
At 6:57 p.m., he addressed public safety during hurricane season with practical advice for families: “The first half of hurricane season has luckily been quiet. But don’t let your guard down. Stay prepared.
Here’s some steps you and your family can take:
Create a necessity kit (batteries, food, blankets, flashlights, pet supplies, first aid kit, etc.)
Keep important” (July 27, 2025).
Mast has served as U.S. Representative for Florida’s 21st District since replacing Patrick Murphy in 2017 and previously held office in the Florida House of Representatives. Born in Grand Rapids, Michigan in 1980 and currently residing in Fort Pierce at age 42, Mast earned his BA from Harvard University Extension School in 2016.
