This is reported by CNN citing informed sources.
According to them, during the conversation, Trump intends to discuss the upcoming in-person meeting with the leader of Russia. The American politician's team began preparations for a phone call with Putin several weeks ago, but it remains unclear whether a date has been finalized.
Trump's team hopes to quickly start working on a plan to resolve the Russia-Ukraine war — hence the need for a meeting with the Russian leader.
It should be noted that Donald Trump stated he plans to meet with Putin "very soon" after taking office on January 20. Reports from Switzerland and Serbia indicated they are ready to organize the meeting.
The team of the newly elected U.S. president is also preparing for a phone call with the Russian leader.
Trump himself pointed out that previously “everyone understood” that Ukraine could not join the Alliance, criticizing the current American president Joe Biden for promising NATO membership to Kyiv.
