Former and future first lady Melania Trump has criticized Barack and Michelle Obama for making her and Donald 's first move into the White House "challenging," accusing the former first couple of "withholding" information that would have smoothed the transition between administrations.

While all of the living former presidents will attend Monday’s inauguration, they have declined Donald Trump’s invite to the celebratory luncheon afterward. Former Presidents Barack Obama, Bill Clinton, nor George W. Bush will be there — and that might be making the biggest statement of all.

Former President Barack Obama was spotted at the inauguration of Donald Trump. See pictures of the former president here.
