John Oliver hilariously trolls Trump with educational ads airing during TV shows the president watches

John Oliver announced a brilliant plan to bring President Donald Trump up to speed on basic facts he'll need to serve as the nation's chief executive.

The British comedian and host of HBO's "Last Week Tonight" is worried -- like many Americans and others around the world -- that the American president doesn't understand fundamental principles of constitutional law and other important topics, such as the nuclear triad or geography.

So Oliver has bought advertising during cables news shows Trump regularly watches, such as CNN's "New Day," MSNBC's "Morning Joe" and Fox News' "Fox & Friends."

“This is one small way we wanted to try to sneak some useful facts into his media diet," Oliver said.

Trump bases his policies on "half-remembered" information he picks up from cable news or "frighteningly unreliable" websites, such as Breitbart News and InfoWars, Oliver said.

“Trump’s relationship with the truth is going to be of profound importance going forward,” Oliver said. “Trump’s reality can change with a single sentence.”

In one ad, an actor dressed as a cowboy explains basic facts about the Geneva conventions and black people.

"No all black people live in the inner city, and not all people in the inner city are black," the actor explains to the president. "Now, I know it can sometimes feel as if you're the only person in the world, but as you can see here, there are actually many non-you people. We call those 'other people.'"

The educational ads aimed at an audience of one will start airing Monday morning, from 830 to 9 a.m., Oliver said.
