After a phone call Monday between Trump and President Vladimir Putin of Russia, Trump appears to be walking away from negotiations for a ceasefire between Russia and Ukraine.

President Trump has repeatedly shifted his positions on Ukraine to accommodate Russian President Vladimir Putin, even as Putin has given very little in return. Why it matters: Trump's critics claim he's getting played — that Putin has no intention of making peace and is stringing him along.

Konstantin Kosachev stated that a so-called “peace memorandum” is in its final stages and may be sent to the Ukrainian side within days. The document, he claims, is intended to lay the groundwork for a possible peace agreement.
