Welcome to the News Hour. A stunning scene unfolded in the Oval Office today as President Trump met with South Africa's president and unexpectedly played videos that Mr. Trump said proved his allegations that South Africa is committing genocide against white farmers there. The South African delegation pushed back denying the debunked claim. Here's Nick Schifrin.

What would it take for you to be convinced that there's no white genocide in South Africa?

Well, I can answer that for president.

Today, South African President Cyril Ramaphosa took a leap of faith.

It will take President Trump listening to the voices of South Africans.

Convinced he could change President Trump's mind on live TV.

It will take President Trump to listen to them.

At first, he was ambushed.

Turn the lights down and just put this on.

It's right behind you.

President Trump used videos of radical South African politicians calling for racist violence.

And newspaper clips.

Death. Death. Death.

To back up his claim of genocide against white farmers, dozens of whom recently arrived in the U.S. as refugees.

They're taking people's land away, and in many cases those people are being executed.

At first, Ramaphosa appealed to facts.

South Africa's parliament includes small, radical parties who aren't in government.

And white Afrikaners, an ethnic minority that created and led the now defunct apartheid regime,

are being killed alongside black farmers because of crime, not racism, according to police data.

When they kill the white farmer, nothing happens to them. No.

There is quite...

Nothing happens to it.
