Donald Trump's former personal doctor is coming out against the president and revealing new information about a controversial letter that was released on his health during the 2016 election. Dr. Harold Bornstein has revealed that a letter praising Trump's health was not written by him, but rather by Trump himself.

Trump's doctor turns

Not long after Donald Trump announced his campaign for president, questions were raised about his health.

At the time, Trump was 69-years-old and would be in his 70s if he was elected. Due to the former host of "The Apprentice" not having the best eating habits as well as limited to no exercise, his health was a priority as his popularity increased. In 2015, Trump's then personal doctor of close to 30 years, Dr. Harold Bornstein, released a letter in praise of the billionaire real estate mogul's health, claiming Trump had "extraordinary physical strength and stamina." In addition, Bornstein wrote, "I can state unequivocally, will be the healthiest individual ever elected to the presidency."

Fast forward to present day and Harold Bornstein has a different story, telling CNN on May 1 that Donald Trump was the one who told him what to write in the aforementioned letter.

"He (Trump) dictated that whole letter. I didn't write that letter," Bornstein admits. "I just made it up as I went along," he added. Bornstein's remarks come on the same day he revealed that Trump associates raided his office earlier this year looking for the president's medical records.

Twitter erupts

In response to the news that Donald Trump allegedly wrote his own doctor's letter, critics took time to fire back.

"As though anyone questioned who wrote this letter," one tweet read.

"This is not breaking news, this was obvious from the beginning," a Twitter user wrote.

"Trump is such a compulsive liar - how can anyone take him seriously," another tweet stated. "The real story is that there idiots that still think he’s a good President," an additional tweet noted.

"I do not know where to begin with this.

This man, who is used to dictating his 'truths' and has managed his life like this for decades, somehow got elected the President of the United States. I am speechless," a social media user wrote. "That is not shocking. We all knew that when we intelligent adults read the letter," a follow-up tweet read. As the backlash continues to pour in, it was made clear that the opposition to Donald Trump was not coming to an end anytime soon.
