Donald Trump's envoy, Michael Witkoff, has arrived in Moscow, marking his fifth visit to the Russian capital since January. This trip occurs ahead of the impending deadline for a potential ceasefire agreement in Ukraine. The purpose of Witkoff's visit remains undisclosed, but it's generating speculation given its timing and the ongoing diplomatic efforts to de-escalate the conflict between Russia and Ukraine. His repeated visits highlight the continued back-channel communications between Trump's circle and the Russian government.
