Trump ripped into the Russian leader, accusing him of being “all talk” after months of U.S. efforts to broker a deal to end the war he started by ordering an invasion of Ukraine, and said he’d prefer not to use the powerful secondary sanctions he’s threatened but stressed that the war “has got to stop.”

U.S. President Donald Trump's decision to ramp up arms shipments to Ukraine is a signal to Kyiv to abandon peace efforts, Russia said on Thursday, vowing it would not accept the "blackmail" of Washington's new sanctions ultimatum.

Senate Majority Leader John Thune says Republicans will vote on a Russia sanctions bill once Trump approves it, as pressure mounts on Moscow to negotiate peace in Ukraine.

In a major shift toward Ukraine, Trump announces a plan to send weapons, including Patriot systems, and threatens 100 percent tariffs if Russia doesn’t reach a deal soon.

New developments Tuesday reinforced the idea that President Donald Trump has significantly shifted his view of the Ukraine war.

What sanctions will be imposed on Russia? The US could target exports, the Nord Stream 2 gas pipeline and even Vladimir Putin and his inner circle.
