19 outlandish conspiracy theories Donald Trump has floated on the campaign trail and in the White House

In May 2011, reporters swarmed now-President Donald Trump as he exited the Hyatt in Washington, DC, after the White House Correspondents' Dinner.

Many wanted a response from Trump, who had just watched President Obama deliver jokes that night about Trump's constant questioning of the legitimacy of Obama's birth certificate.

Years later, Trump is still not convinced of the legitimacy of Obama's birth certificate. But this was perhaps the first of numerous debunked or unverified conspiracy theories that Trump has entertained during his time in the political spotlight.

Throughout the 2016 campaign and while in the White House, Trump has floated theories fueled by the conspiratorial-minded corners of supermarket tabloids and the internet, something unprecedented in modern politics. He's often used them as weapons against his opponents.

Here are some of the most notable conspiracy theories Trump has entertained:
