Good Tuesday morning. Here are some of the stories making news in Washington and politics today.

• President Trump has concluded that his tariff threat worked to force Mexico into an agreement. His increasing confidence that the levies can help accomplish his goals without harming the United States sets up an even more tumultuous period ahead for businesses, consumers and foreign countries.

• The Mexican foreign minister said Monday that no secret immigration deal existed between his country and the United States, directly contradicting Mr. Trump’s claim on Twitter that a “fully signed and documented” agreement would be revealed soon.

• The Justice Department agreed to turn over key evidence from Robert S. Mueller III’s investigation to the House in return for calling off a criminal contempt vote.
