President Donald Trump warned Russia Monday that it may face "severe tariffs" if a peace deal with Ukraine isn't negotiated.

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.”

In a significant shift toward Ukraine, Trump announces a plan to send advanced weaponry including Patriot systems, and threatens 100% tariffs if Russia can’t reach a peace deal soon.
