U.S. sanctions Colombia's President Petro and his family

• The sanctions allege Petro has ties to the trade in illicit drugs.

Catch up quick: Colombia and the U.S. have traditionally been close allies, but relations have fallen apart since Trump took office.

• Colombia was one of the first targets of Trump's tariff threats, early in his term, and more recently he's had a war of words with Petro over drug trafficking and the U.S. attacks on boats in the Caribbean.
• In one social post, Trump accused Petro of having a "fresh mouth."
• Last month, the United States pulled Petro's visa after the Colombian leader demonstrated outside the United Nations by calling on U.S. troops to disobey Trump over his Israel policy and said citizens should "point their rifles ... toward the tyrants and the fascists."

The other side: Petro quickly took to social media to denounce the sanctions, saying he's been fighting trafficking for decades.

• "A complete paradox," he wrote.
