President Trump in a social-media post urged Russian President Vladimir Putin to make a deal, in his most forceful and public effort to end the war in Ukraine.

President Trump is turning up the heat on Russian President Vladimir Putin in his first days in power, seeking to pressure Russia’s leader to come to the negotiating table for a deal to end the war in Ukraine.

President Trump has demanded Russia stop its “ridiculous war” with Ukraine or face stiffer penalties — but the U.S. doesn’t appear to have much financial leverage left after a raft of prior sanctions.
