Donald Trump left the White House on Friday to take part in his longest foreign trip since becoming president. After announcing on Twitter about his first stop, Trump was met with mockery from critics.

Trump in Hawaii

Years before Donald Trump decided to run for president, he stuck his neck out in the world of politics. The first time the former host of "The Apprentice" got political in a mainstream way was back in 2011 when he quickly became the highest profiled name to back the controversial "birther" movement, which accused former President Barack Obama of faking his birth certificate in order to run for the president.

Trump and company also claim that Obama was hiding the fact that he was actually born in Kenya, while accusing him of having his documents forged to say he was an American citizen born in Hawaii. Despite the overwhelming evidence proving otherwise, Trump never fully backed off the allegations, which he attempted to distance himself from during the 2016 presidential election. While the billionaire real estate mogul was able to weather the storm of controversy and win the election, Trump found himself in the awkward position of meeting Obama at the White House following his inauguration. Though the two were cordial at the time, Trump has since lashed out at the former president on more than one occasion.

As seen on his Twitter account on November 3, Trump commented about his arrival in Hawaii.

Taking to his Twitter feed on Friday night, Donald Trump posted about the first stop in his 12-day foreign trip.

"Getting ready to land in Hawaii," Trump tweeted, before adding, "Looking so much forward to meeting with our great Military/Veterans at Pearl Harbor!"

Donald Trump's stop in Hawaii will be followed by trips to China, Japan, the Philippines, South Korea, and Vietnam.

As the president landed in the Aloha State, those who oppose him were quick to point out that it's the birthplace of Barack Obama.

Twitter reacts

Just after Donald Trump sent out his tweet about visiting Hawaii, social media critics wasted no time firing back. "Say hi to Barack for me," one tweet read.

"Hawaii! The Birth Place of Barack Obama. Wait. Trump, Is that in the United States?" another tweet added.

"That's where Obama was born!!" one Twitter user stated.

"Home of the best president ever...@BarackObama!!" yet another tweet pointed out. "Ah, the birthplace of Barack Obama. Beautiful," a follow-up tweet noted. As the trolling continued, it proved that many Americans weren't going to let Donald Trump forget about his debunked birther conspiracy anytime soon.
