Five days into his presidency, Donald Trump has acted swiftly to dismantle Barack Obama’s legacy, issuing executive orders cutting federal funding to women’s health groups abroad if they discuss abortion, green-lighting the Keystone XL and Dakota Access pipelines, and scaling back the Affordable Care Act. While his press secretary Sean Spicer has been busy holding daily press briefings and generally evading journalists’ questions about the Trump presidency, Trump himself has been issuing gag orders against various federal agencies. He’s instructed employees at the Environmental Protection Agency—which has had its contracts and grants frozen—and the U.S. Department of Agriculture not to communicate with the press or the public, instituting a media blackout.

Not everyone within the federal government is staying quiet, however. On Tuesday, the Twitter account for South Dakota’s Badlands National Park—a subsidiary of the National Park Service—began tweeting out climate change facts, in apparent defiance of the gag order. Someone working for the national park’s social media team went rogue and started posting climate change facts from the National Wildlife Federation’s Web site in 140-character bursts. (Trump, who can generously be described as a climate change skeptic, has previously called called climate change a “hoax” engineered by the Chinese.)

The National Park’s tweets were retweeted thousands of times before they were suddenly deleted later Tuesday afternoon.

Minutes after the tweets disappeared, the Democratic National Committee fired off a simple five word statement in response: “Vladimir Putin would be proud.”

It isn’t the first time the National Park Service has used Twitter to protest Trump. On Friday, the new administration ordered the Interior Department’s digital team to stop tweeting after it reposted side-by-side photos comparing the size of Obama’s inauguration crowds in 2009 and the number that turned out for Trump. In a letter to N.P.S. employees obtained by Gizmodo on Friday, the agency said: “We have received direction from the Department through [the Washington Support Office] that directs all [Department of Interior] bureaus to immediately cease use of government Twitter accounts until further notice.” (It is longstanding protocol for the agency not to issue crowd size estimates.)

Trump’s team later claimed that they gave the order to stop tweeting out of fear that the N.P.S. account had been hacked. The N.P.S. has since deleted the retweet, and issued a follow-up statement on Saturday. “We regret the mistaken RTs from our account yesterday and look forward to continuing to share the beauty and history of our parks with you,” the agency said.
