This was reported by Politico newspaper, citing a senior representative of the US administration.
“During the telephone call this week, the leaders had heated disagreements on topics such as NATO, the Nord Stream 2 gas pipeline between Russia and Germany, and relations with China,” the text says.
It is noted that the White House has not yet commented on this information.
