Washington: US President Donald Trump dropped in unannounced on roughly 100 schoolchildren touring the White House on Tuesday, greeting them beneath a picture of his vanquished election rival Hillary Clinton.
As tours restarted at the White House after a brief interval, Trump greeted pupils at the Briarwood Christian School in Birmingham, Alabama.
The location of his surprise greeting was the ground floor center hall beneath a portrait of Clinton - one of a series of paintings of former first ladies.
White House tours are normally self-guided, lasting about 45 minutes. They do not normally include a meeting with the president.
