Shortly after entering Congress, Posey introduced legislation (H.R. 1503) to amend the Federal Election Campaign Act of 1971 to require candidates for the presidency “to include with the [campaign] committee’s statement of organization a copy of the candidate’s birth certificate” and supporting documentation.^[15] Introduced without the Republican leadership’s knowledge,^[16] the bill, Florida Today wrote, “stems from fringe opponents of President Barack Obama who, during the 2008 election campaign, questioned whether Obama was born in Hawaii”. Florida Today added that Posey’s office “does not question Obama’s citizenship.”^[17] Posey said his motivation was to “prevent something like this from happening in the future” by requiring “the birth certificate up front and take [the issue] off the table”. His initiative was strongly criticized by Florida Democrats, who accused him of trying to “fan the rumors on the extreme fringe of the Republican Party” and “pandering to the right wing”.^[18] Posey said that there was now “no reason to question” that Obama is a U.S. citizen.^[19] The 111th Congress never voted on the bill.^[20]

In 2016, Posey sponsored legislation to reauthorize and reprioritize funding to clean up America’s estuaries signed into law by President Obama.^[21][22][23]

At a May 2018 hearing in the Science, Space and Technology Committee, Posey promoted the claim that climate scientists in the 1970s believed the Earth was cooling;^[24] expressed skepticism that humans contribute to climate change, asking whether climate change was occurring because carbon dioxide captured in permafrost was now leaking out;^[24] and asked whether warming would be beneficial for habitats and to people.^[24] Posey said, “I don’t think anybody disputes that the Earth is getting warmer; I think what’s not clear is the exact amount of who caused what, and getting to that is, I think, where we’re trying to go with this committee.”^[24]

In June 2021, Posey was one of 49 House Republicans to vote to repeal the AUMF against Iraq.^[25][26]

Posey was among 19 House Republicans to vote against the final passage of the 2022 National Defense Authorization Act.^[27]
