Frustrated by the Trump administration's anti-science stance and an apparent social media blackout of EPA and other agencies, advocates are making plans for a march.
The nonprofit investigative website Pro Publica quoted an EPA employee who said that unlike a hiring freeze, often seen during administration transitions, a freeze on grants and contacts was "extraordinary" and unprecedented.
However, one employee told the publication that he couldn't recall a similar event happening in 10 years with the agency.
EPA employees have privately expressed concerns over their jobs and censorship of their work, although the Guardian could not confirm claims that political vetting of science was now official doctrine.

Ericksen said the agency wants to make sure it's speaking with one voice as it transitions from one administration to another. The EPA, which regulates clean air and water, displays on its site in-depth information on the basics of climate science, actions the agency is taking to reduce emissions and data showing USA emissions over the years.
The EPA's policy, like those of other technical agencies within the government, is created to encourage its scientists to participate in the scientific process. That includes conducting and publicising research into global warming - research that will now have to be approved by the government and which may be deleted entirely from the website.
"For too long, we've been held back by burdensome regulations on our energy industry", the White House policy says. Archived versions of those reports remain available, and a 2014 fact sheet on climate change - now missing from the State Department site - also can be found elsewhere. There's a feeling that climate scientists are being targeted.
When asked if climate change fit into that, he repeated that they'll focus on the core mission.
