You've probably heard in the past day or two that the Trump Administration has imposed a "gag order" on the EPA and the USDA. That's the media being drama queens. As with any change of administration, policies are reviewed, and until new policies are put in place and everyone understands them, the new boss doesn't want agencies under him undermining his priorities by making public statements that conflict with them.
For example, the White House doesn't want the EPA posting on Facebook and Twitter about "climate change" in ways that reflect Obama policies but not Trump policies. That's as ordinary as the day is long, and you'll see it at any level of government or within any corporation when new leadership replaces old and policies are reviewed.
