Any government official can hold press conferences and make press releases just like they used to. However in practical terms the reach of those messages is severely limited. Did you know the President has a weekly radio address?

Besides inauguration day, do you remember reading official documents on the whitehouse.gov website? I never have. Nor have I ever gone to AOC's official house.gov site to read her messages. But I do know what she's saying on Twitter.

Not to belabor the point but where the message is delivered is a huge factor in whether or not the message will even be noticed.
