In a first, Obama late for last UN General Assembly address

For the first time, a US President was not the second speaker at UN's annual General Assembly's General Debate as Barack Obama arrived late for his last address as the Head of State.
Obama missed his turn as the second speaker which promoted President of the General Assembly to call Chad's leader, who was the next speaker on the list, to make his national statement.
The US has traditionally been the second speaker in the General Debate after Brazil.
Today's address was Obama's eighth and final address to the UN General Assembly as America's Commander-in-Chief.
After Brazil's President Michel Temer finished his address, President of the General Assembly Peter Thomson said Obama is delayed and has not yet arrived for his speech to the General Assembly.

Not waiting for the US President to show up, Thomson proceeded on to the next speaker on the list, inviting Chad's leader to make his address.
