Rob Porter and Trump: Explaining the story in three simple ways

In a presidency where headline-grabbing news stories have the life expectancy of mayflies, the furore surrounding former White House aide Rob Porter has had notable resiliency. What's it all about?

The Daily Mail first printed allegations that the president's staff secretary had a history of spousal abuse on 6 February.

A day later, the Intercept published photographs of Porter's first wife with a black eye, which she said he had given her during their Italian honeymoon in 2005.

From there, other outlets reported that the FBI uncovered details about Porter's history during its background checks and that the aide had been working with a temporary security clearance for the duration of his time in the White House.

By 7 February, the White House announced that Porter would resign once a replacement had been selected. The following day, its press secretary told reporters Porter had permanently left that morning.

For more than a week since then, it has dominated the news in the US, with every development endlessly scrutinised and dissected.

So what are the three key points to remember?
