A Florida manatee appears to have endured getting “TRUMP” carved into its back, prompting a nonprofit group to offer a $5,000 reward for information leading to a conviction.

The U.S. Fish and Wildlife Service and Florida’s Fish and Wildlife Conservation Commission began an investigation after the manatee with President Trump’s name etched into its back was discovered in the headwaters of the Homosassa River. The Center for Biological Diversity is offering the $5,000 prize for anyone who can prove who is behind the act.
