It is hard to believe given current events, but in normal times Presidents leave office with grace and dignity, and a tradition of leaving handwritten notes has emerged

It may seem hard to fathom after Donald Trump’s four-day temper tantrum, but up to now US Presidents have left the White House with dignity and grace.

One particular tradition shows the solidarity that has previously existed between the commanders-in-chief as they switch.

Departing Presidents often leave handwritten notes to their successor, offering advice and wishing them success.

It remains to be seen whether Trump will do the same if his exit is confirmed, but his recent behaviour suggests this is unlikely.

When he arrived in the Office he found a friendly letter from Barack Obama – despite having years questioning whether Obama was actually born in the US.
