Ever since announcing his campaign for president last summer, Republican front runner Donald Trump has found his name in the headlines due to making controversial and questionable comments along the campaign trail. While Trump is usually the one that has forced himself into controversy, new light has been shined on an old personal problem.

Trump goes limp

The billionaire real estate mogul has become one of the most intriguing people over the last year, with many wondering if Trump is as authentic as he appears to be when he gets in front of the camera.

When Politico sat down for an interview with a group of biographers, personal information about Trump's sex life was highlighted, and the former host of "The Apprentice" won't be happy about it.

In 1993, Hart Hunt III released a book titled, " Lost Tycoon: The Many Lives of Donald J. Trump," which gave a very specific reason for why Trump's first marriage ended in divorce. "What broke up Trump’s first marriage? Harry Hurt III writes that Ivana 'confided to female friends that Donald had difficulty achieving and maintaining an erection.'"

The information received little recognition at the time, but now with Trump in the brightest spotlight of his life, it has returned to haunt the man that bragged about the size of his genitals during a live Republican debate.

Trump's erectile dysfunction became nothing more than a tidbit after it was also revealed that his first wife, Ivana, gave a deposition that claimed the future GOP front runner raped her while they were still married. Years after the deposition, Ivana walked back her comments, saying in a statement released by her lawyers that the rape never actually occurred.

Obama hatred

Also during the Politico round-table, Michael D'Antonio, author of "Never Enough: Donald Trump and the Pursuit of Success," spoke about Trump's feelings on President Obama. D'Antonio called the billionaire's hatred of Obama "sincere and visceral." Citing his first meeting with his subjectin 2013, D'Antonio recalls how Trump would go on endless rants about his disdain for the president, stating that it just got "to the point where he just was irrational."

Primary status

Despite the recent accusations against him, Trump is still the odds on favorite to become the GOPnominee.

With 994 delegates, Trump is inching his way to the required 1,237 needed to secure the nomination before the convention in July. If Trump is unable to reach his goal, a brokered convention will take place.
