Laurence Francis Rooney III (born December 4, 1953) is an American politician and diplomat who was a U.S. representative for Florida's 19th congressional district from 2017 to 2021.

Rooney spent $4 million of his own money and far outspent his opponents in an election that was shortened due to the timing of Clawson's late announcement.

Rooney received an unprecedented endorsement from Rick Scott, who is his neighbor in the Naples, Florida Port Royal community.

[20] As of 2017, Rooney has a "B" rating from the NRA Political Victory Fund, indicating a voting record that generally supports gun rights.

Rooney also supports a mandatory 3-day waiting period for all gun sales, a ban on bump stocks, and raising the minimum age to purchase any firearm to 21.

[26] However, in response to questions on if he would support reinstating the Federal Assault Weapons Ban, Rooney replied, "How willing are we to throw the Constitution out the window?

"[27] Rooney has stated that his support of any new gun control legislation is contingent on the inclusion of a rider of the Concealed Carry Reciprocity Act of 2017.

A revenue-neutral carbon fee is an efficient, market-driven incentive to move toward natural gas and away from coal, and to support emerging alternate sources of energy.

In an op-ed published on Politico in September 2019, Rooney declared, "I’m a conservative Republican and I believe climate change is real.

It’s time for my fellow Republicans in Congress to stop treating this environmental threat as something abstract and political and recognize that it’s already affecting their constituents in their daily lives.

He has voted to delay enactment of ozone standards,[35] and to repeal a rule requiring energy companies to reduce waste and emissions.

[39] At the time of Rooney's stated position on DACA, a large majority of American citizens were in support of the program,[40][41] including according to an August 31 through September 3, 2017 poll[42] where 57% of self-identified as Republican voters.

[52] In a December 26, 2017, MSNBC interview, Rooney, called into question the integrity of the FBI and Justice Department, who were conducting an investigation into Russian State interference in the 2016 elections and any possible collusion between Russia and the Donald Trump presidential campaign along with any related crimes, alluded to a "deep state", presumably seeking to undermine the Trump presidency.
