A new presidential administration typically brings significant changes to federal government websites. What is not typical, however, is the pressure faced by executive agencies in the second Trump administration to remove data and take down websites that conflict with the president's political views as outlined in his executive orders.
It has become increasingly common for government data sets that were previously publicly available to be removed. Some of these datasets may be altered and made available again, while others may remain offline indefinitely.
