Big game hunters won't be able to ship their elephant body part trophies from Africa just yet.

This week the Trump administration announced it would lift President Obama's ban on body parts from African elephants shot for sport. 

But President Trump tweeted Friday evening that he would put that decision on hold:

The U.S. Fish and Wildlife Service said Thursday that allowing elephants from Zimbabwe and Zambia to be brought back as trophies would raise money for conservation programs. 

“Legal, well-regulated sport hunting as part of a sound management program can benefit certain species by providing incentives to local communities to conserve those species and by putting much-needed revenue back into conservation,” the agency said in a statement.

But the decision has caused a furor among animal rights activists.

“What kind of message does it send to say to the world that poor Africans who are struggling to survive cannot kill elephants in order to use or sell their parts to make a living, but that it’s just fine for rich Americans to slay the beasts for their tusks to keep as trophies?” asked Wayne Pacelle, president of the Humane Society of the United States.
