KEY POINTS

  • Obama roasted Trump's birther theory during a 2011 White House Correspondents' Dinner
  • Trump had once claimed that Obama was not born in the United States
  • Experts believe the public humiliation pushed Trump to run for the presidency in 2015

Former President Donald Trump was allegedly fuming when then-President Barack Obama mocked his “birther” conspiracy theory at the 2011 White House Correspondents’ dinner, according to a new memoir. 

During the annual Washington dinner, Obama roasted Trump and his promotion of conspiracy theories surrounding his predecessor’s birthplace, former New Jersey Gov. Chris Christie writes in his new memoir. The birther theory began in 2011 when Trump demanded Obama to release his birth certificate and questioned whether he really was born in the United States. 

“As some of you heard, the state of Hawaii released my official long-form birth certificate. Hopefully this puts all doubts to rest,” Obama joked. “But just in case there are any lingering questions, I am released my official birth video.”

Following Obama’s jokes, Trump appeared to be glowering, Christie states in his new memoir, “Republican Rescue: Saving the Party from Truth Deniers, Conspiracy Theorists, and the Dangerous Policies of Joe Biden.”

"I spoke to Donald after the dinner," Christie wrote in the book, a copy of which was obtained by The Business Insider in advance. "He was pissed off like I'd never seen him before. Just beside himself with fury."

Some experts believe the public humiliation Trump suffered that night helped fuel his desire to run for the presidency in 2015.

In Christie’s memoir, he also urged Republicans to renounce people promoting conspiracy theories and truth deniers. While the former New Jersey governor did not directly name Trump, he did slam Rep. Marjorie Taylor Greene, R-Ga., for showing support for the former president and his conspiracy theories. 

Christie also acknowledged that the 2020 election was not stolen — the complete opposite of what Trump and some Republicans have claimed. 

“Joe Biden won. Donald Trump did not. Any claim to the contrary is untrue,” he wrote in his book, a copy of which was also obtained by The New York Times.

The Republican lawmaker was one of Trump’s staunch supporters during his 2016 presidential campaign. He has also led Trump’s transition effort until he was tapped to lead the former president’s opioids commission. 

Besides being the former governor of New Jersey, Christie is also a former presidential candidate. It is unclear whether he plans to run for the presidency in 2024.
