Today, two presidents known for their fiery rhetoric toward each other met in the Oval Office and apparently put their acrimony behind them.

Colombia's president Gustavo Petro has long been a critic of President Trump and the U.S. itself.

But Mr. Trump this afternoon praised Petro and did not repeat previous threats of military action.

And in a press conference tonight, Petro said the meeting eased tensions between Trump

and all of Latin America.

Nick Schifrin reports.

Today at the White House, a Colombian president who for decades criticized what he calls

American imperialism was all smiles for the man he recently dubbed a would-be king.

President Trump greeted Gustavo Petro warmly, offered a personal tour of what he's labeled

the presidential walk of fame, and wrote Petro a letter, a great honor.

I love Colombia and inscribed his art of the deal, you are great.

I thought he was terrific.

You know, he's very. You get a long great.

Tonight, Petro said the meeting diffused regional tensions.

He gave me a red cap that said, make America great again.

And I wrote with a pen and put an S and said, make America's great.

And that can only be done on the basis of mutual respect.

That is a far cry from months of mutual maliciousness.

Colombia is out of control, and now they have the worst president they've ever had.

He's a lunatic who's got a lot of problems, mental problems.

We must respond to defend people's rights, the rights of democracy not to be governed by tyrannies.

He has cocaine mills or cocaine factories. He's not going to be doing it.
