Randy Feenstra, U.S. Congressman representing Iowa’s 4th district since 2021, used his social media platform to address issues affecting Iowa agriculture and national tax policy in a series of posts published on September 25 and 26, 2025.

On September 25, Feenstra highlighted concerns about the global phosphate market and its impact on Iowa farmers. He stated, "With China controlling 40% of global phosphate production, it’s important that we ensure that Iowa agriculture has access to affordable phosphate. It’s why I joined @SenJoniErnst in requesting that phosphate be added to the Critical Minerals List."

The following day, Feenstra commented on recent federal tax policy changes. On September 26, he wrote, "On Independence Day, President Trump and Republicans STOPPED the largest tax increase on families, farmers, workers, and small businesses in U.S. history. Now, with these tax cuts and pro-growth policies enacted, working families will see real relief!" In another post later that day he added: "Republicans prevented the largest tax increase on families, farmers, workers, and small businesses in U.S. history. Democrats openly welcomed the largest tax increase in U.S. history."

Feenstra's advocacy for including phosphate on the Critical Minerals List reflects ongoing debates about agricultural supply chains and reliance on foreign sources for key inputs like fertilizer components. Phosphate is an essential nutrient for crop production; China is currently responsible for approximately 40% of global output.

A member of Congress since replacing Steve King in 2021 and a former Iowa state senator from 2009 to 2021, Feenstra has emphasized support for rural economies and local farmers throughout his career. Born in Hull, Iowa in 1969 and a graduate of Dordt University (BA '91), he continues to reside in his hometown while serving constituents across northwest Iowa.
