WASHINGTON (AP) — President Donald Trump on Monday threatened Russia with steep tariffs and announced a rejuvenated pipeline for American weapons to reach Ukraine, hardening his stance toward Moscow after months of frustration about unsuccessful negotiations for ending the war.

Trump also revealed that Putin had recently offered to assist in mediating between Israel and Iran during their brief June conflict — an offer he declined. “I said, ‘No, no, you help me get a settlement with you, with Russia,’” Trump recounted. “And I think we're going to be doing that too.”

Trump said the United States would put secondary tariffs on countries that do business with Russia if a peace deal is not reached in 50 days.
