Before Donald Trump decided to run for president, he publicly questioned whether or not Barack Obama was an American citizen. After nearly a year in office, reports state that Trump is still questioning the former president's birth certificate.

Trump's birther problem

In the years prior to becoming the 45th President of the United States, Donald Trump was the highest profiled voice in what became known as the "Birther Movement." The idea behind birtherism was that Barack Obama was not born in Hawaii, but rather in Kenya where is father was born, and that he faked his birth certificate in order to run for office.

Despite Obama providing all the necessary documents to prove otherwise, the former host of "The Apprentice" used his popularity to keep the conspiracy theory alive. As time moved on, birtherism wasn't just isolated to the far right of the political spectrum, but was seen on mainstream news programs, with Fox News hosts like Sean Hannity highlighting the issue on a routine basis. The rise of the Tea Party only helped the cause stick around, which eventually became a running joke used by liberals to mock gullible conservatives. During the 2016 election, Trump avoided discussing Obama's birth certificate, but it appears he's not letting the theory go. According to the New York Times on November 28, the commander in chief has been questioning the issue with multiple Republican congressmen.

As reported by the New York Times on Tuesday night, Donald Trump has apparently never let go of his birtherism. "Mr. Trump has used closed-door conversations to question the authenticity of President Barack Obama’s birth certificate," the NYT reports, quoting Republican senator who wished to remain anonymous.

Another senator said he couldn't help but laugh as Donald Trump brought up Barack Obama's birth certificate at a recent meeting, explaining that the president "has had a hard time letting go of his claim that Mr.

Obama was not born in the United States."

Social media reaction

After the news that birtherism is still on his mind of Donald Trump, critics of the president couldn't help by give their thoughts. "I truly hate him," one tweet read, which was replied by another Twitter user who wrote, "Hate isn't even a strong enough word anymore."

"Please please please can we get him out of there now?

Isn't this enough?" another Twitter user asked. "Trump is just a crazy fool, but his birther base are the biggest idiots of our time," an additional tweet stated.

"He is so obsessed with him. He Can’t just let him go," yet another tweet noted. "He’s still so jealous of Obama. Odd fixation of someone he will never measure up to," a social media user wrote. The mockery continued as Donald Trump's fixation over Barack Obama remains alive and well.
