Badlands National Park on Tuesday posted several facts about climate change on its official Twitter account, then deleted them.
Before being deleted, the tweets were retweeted thousands of times and earned praise as defiance of the Trump administration. In his campaign, President Trump said "no one really knows" if climate change is real, a break with mainstream science. He has also vowed to eliminate the Obama administration's policies on climate change.
The tweets came after the Trump Administration ordered some scientists within the federal government into silence.
Employees within the US Department of Agriculture have been banned from sharing its research with the public — including on social media. The Environmental Protection Agency was similarly banned from providing updates to reporters or posting to social media as its grants and contracts were frozen.
The climate change tweets were posted by a former employee, and park officials decided to delete them because the account had been "compromised," a National Parks official told BuzzFeed News.
"Several tweets posted on the Badlands National Park's Twitter account today were posted by a former employee who was not currently authorized to use the park's account. The park was not told to remove the tweets but chose to do so when they realized that their account had been compromised."
Quartz reported the Badlands park superintendent didn't know about the tweets; staff have been busy responding to a blizzard, and the social media manager was working from home.
National parks are encouraged to use Twitter to post park and public safety information, the National Parks official told BuzzFeed News. But, he added, parks should stay away from "content related to national policy issues."
"At this time, National Park Service social media managers are encouraged to continue the use of Twitter to post information relating to public safety and park information, with the exception of content related to national policy issues."
