On Friday Donald Trump visited the US state of Hawaii. He didn't receive the traditional warm welcome associated with the island.

The President was there to visit Pearl Harbour and one of his own hotels but it was the protests and a number of signs that grabbed all the attention.

In case you weren't aware, Hawaii is the birth place of Trump's predecessor in the White House, Barack Obama.

Despite the former President being 100 per cent American, his place of birth was constantly debated during his time in office, mainly by Trump.

The New York billionaire was convinced that Obama was actually born in Kenya and in an infamous tweet claimed his birth certificate was fake.

It would appear that the people of Hawaii have a very good memory and a great sense of humour to boot.

As Trump and Melania began their visit there were treated to a series of signs reading "Welcome to Kenya."

Other signs were also on point.

Twitter loved the signs and the protestors.

We can't imagine Trump would have been too happy to see these signs mocking his wild theories.

He would have been even more irked to hear Obama himself make a joke about the speculation.

Earlier this week, Obama spoke at the Obama Foundation's first global summit in Chicago.

The Independent quote him as saying:

The reason I’m so excited to see you all here today in part is because this is where I started. This isn’t where I was born, I was born in Kenya. That's a joke.
