#Republicans = 6 (Kristi Noem, Kevin Roberts, Todd Kincannon, Mehmet Oz, Mike Bost, Greg Gianforte)

I'm not counting George Santos, because he merely created a GoFundMe for the dog of a homeless vet to get lifesaving surgery, and then took the money for himself.
https://www.cnn.com/2023/01/18/politics/george-santos-veteran-dog-gofundme/index.html

I'm not counting Mike Huckabee's son, because he wasn't a politician.

I'm only counting Kristi Noem once, even though she called for Joe Biden's dog to be killed.
https://www.nytimes.com/2024/05/05/us/politics/kristi-noem-biden-dog.html

I'm not counting Mitt Romney, since he merely terrified and endangered his dog when he put it in a carrier, strapped it to the roof of his car, and drove for 12 hours from Boston to Ontario. He had to stop once to hose off the dog's diarrhea dripping down the car's back window.

Update. I originally said the dog died in this incident. But the dog did not die.
https://en.wikipedia.org/wiki/Mitt_Romney_dog_incident

But I must update the count to include Todd Kincannon, once the general counsel and executive director of the South Carolina Republican Party. He fatally choked, stabbed, and mutilated his mother's dog in 2018, saying that God told him to.

I'm not counting Mike Collins (R-GA), since he merely hired a man to be his chief staff who was arrested for kicking a dog (animal cruelty) and whose criminal history had already forced him to resign as Trump’s Georgia state director. https://www.politico.com/news/2022/12/13/gop-operative-brandon-phillips-00073724

I should also count Mehmet Oz (aka Dr. Oz, Republican candidate for the Senate in 2022) who killed 300 dogs and hundreds of other animals in his academic research at Columbia University. On the one hand, his experiments were authorized by the university. On the other hand, they violated applicable rules and the US Department of Agriculture ordered Columbia pay a $2,000 fine.

EDIT. Oz is now #Trump's nominee to run medicare and medicaid.

I'm not counting Rick Scott, who adopted a rescue dog from a shelter, named it Reagan, enjoyed some good publicity for that, and then returned the dog to the shelter. He and the shelter both refused to comment on the dog's fate.

I'm not counting the Wyoming Republican party, which dominated the state legislature in 2021 and passed a bill to exterminate 90% of the state’s wolf population. The bill was so broad that it condoned much torture as well as direct killing.
https://www.outsideonline.com/outdoor-adventure/exploration-survival/wyoming-law-protects-wolf-torture/

I should also count Mike Bost, who shot a neighbor's dog to death in 1986 while it was penned up on the neighbor's property.

I'm not counting Steve Scalise, since he merely introduced a bill to legalize dogfighting.
http://web.archive.org/web/20121023025709/http://thinkprogress.org/politics/2012/07/31/615951/steve-king-dogfighting/

I'm not counting Jim Inhofe, since he killed pigeons, not dogs or cats, in his annual fundraisers.
https://apnews.com/general-news-domestic-news-660e28f92d9249dea9958aba245afdbc

I'm not counting Thad Cochran, since he merely joked that he enjoyed "doing all kinds of indecent things to animals."
https://www.buzzfeednews.com/article/gideonresnick/thad-cochran-jokes-he-used-to-do-indecent-things-to-animals

I'm not counting Donald Trump Jr., since he's not yet a Republican politician and he killed a "rare argali sheep", not a dog or cat.
https://www.propublica.org/article/trump-inc-podcast-donald-trump-jr-went-to-mongolia-got-special-treatment-from-the-government-and-killed-an-endangered-sheep

EDIT (Feb 2025). Italian authorities are investigating his killing of a ruddy shelduck, a rare duck protected under Italian law.
https://www.nytimes.com/2025/02/04/world/europe/donald-trump-jr-duck-hunting-italy.html

I'm not counting Doug Hamlin for torturing a cat to death. He's the new head of the #NRA, not a public official.
https://www.theguardian.com/us-news/2024/oct/14/nra-doug-hamlin-cat-killing

I'm not counting #RFKJr, since he's not officially Republican and he apparently didn't kill the animals (bear cub, whale, goat) whose cadavers he abandoned in a park, decapitated with a chain saw, or cooked on his home grill.

Update (1/28/25). His cousin Caroline Kennedy says "he enjoyed showing off how he put baby chickens and mice in the blender to feed his hawks."

I'm not counting Billy Long, since he merely tried to revoke the tax-exempt status of the Humane Society for backing an effort in Missouri (Long's state) to ban puppy mills.
https://rturner229.blogspot.com/2011/05/billy-long-recipient-of-thousands-from.html

Long is now #Trump's nominee to head the #IRS, where he will control the tax-exempt status of nonprofits.
https://www.nytimes.com/2024/12/04/us/politics/billy-long-irs-trump.html

I started this thread when news broke that Kevin Roberts killed a dog with a shovel. I'm backing up to document that with a link, for the record.
https://www.newsweek.com/project-2025-kevin-roberts-dog-shovel-heritage-foundation-1958543

Kevin Roberts is the President of the #HeritageFoundation and the mastermind behind #Project2025.

When I started this thread, I also assumed that everyone remembered that Kristi #Noem killed her dog and a goat, and even boasted about the killings in her memoir. Here's a link, for the record.
https://www.humanesociety.org/blog/kristi-noem-puppy-killing-scandal

EDIT. The Senate just confirmed Noem (1/25/25) to be #Trump's Secretary of Homeland Security.

When I started this thread, it was well known and #Trump and #Vance were boosting false reports that Haitian migrants in Ohio were killing and eating the pets of their neighbors. Before we forget that episode, here are some links for the record.
