Michelle Obama and Donald Trump have not exactly hidden their disdain for one another. Here's what we know about their ongoing feud.

Former first lady Michelle Obama won’t attend President-elect Donald Trump’s inauguration, though former President Barack Obama will be there, the Obamas' office said in a statement. No reason was given.

Kid Rock, who has been outspoken about his conservative views , was referring to his performance at the 2009 Youth Inaugural Ball , held after Barack Obama ’s first swearing-in. Kanye West and Fall Out Boy were among the other music acts at that event.
