thanks for the news flash, adkhiker! The dodo was a flightless bird endemic to the island of Mauritius, it has been extinct since the 1660s, due to destruction of its habitat and excessive hunting by recently arrived Dutch sailors and invasive predators.
In contrast, the U.S. Endangered Species Preservation Act dates to the 1960s.
I used the dodo bird figuratively here, to illuminate how Trump often makes ridiculous public announcements to showcase his own perceived resoluteness, and his propensity to go against common sense in order to reverse progressive & liberal policies.
