Well, you should be worried.
The media pointed out that there was a lower turn-out for Trump's inauguration than there was for Obama's. In support of this, they showed two photos comparing crowd sizes taken from the top of the Washington Monument. The photo of Obama's inauguration shows crowds stretching from the Capitol to the Washington Monument, whereas the photo of Trump's inauguration showed visibly smaller crowds - there are large patches of ground that simply haven't been filled.
Trump has tried to characterise this as a biased an inaccurate story put forward by an irresponsible media that Preibus has described as trying to "de-legitimise the President".
