Donald Trump has been growing increasingly angry with Putin ignoring his strict 50-day peace deal – with a senator warning what might come next for Russia if he doesn't step in line

But his frustration with Putin has grown. Last week, the president said the United States was taking “a lot of bullshit” from Putin. Today, he authorized a significant shipment of U.S. defensive weapons to Ukraine via NATO and threatened Russia with new tariffs if the war does not end in 50 days.

President Donald Trump appears to have finally realized that his Russian counterpart Vladimir Putin, famed for rigging elections and knocking off opponents, cannot be trusted. “Putin really surprised a lot of people.

President Trump discussed how he came to give up on negotiating with Vladimir Putin, during a meeting with NATO Secretary General Mark Rutte at the White House on Monday, as the U.S. agrees to sell new and more weapons to Europe and Ukraine.

Trump's threat against Russia runs parallel to a Senate-led effort to pass crippling sanctions on countries that buy Russian energy.
