Mr Trump said to Stoltenberg that "When Germany makes a massive oil and gas deal with Russian Federation".
History has shown that Russian Federation has a penchant for attempting to control Europe by cutting off energy supplies.
But Trump's harsh criticism of Germany echoes statements from US officials from past administrations, including Kerry himself, according to recently resurfaced videos, the Washington Free Beacon reported.
Trump praised Poland, noting that the Eastern European country "won't accept the (Russian) gas".
In May 2016, Kerry was speaking in Washington, D.C. together with Energy Secretary Ernest Moniz and European Union High Representative Federica Mogherini, where he expressed concerns about the very same energy project Germany is undergoing. The German Committee on Eastern European Economic Relations (Ostausschuss), which unites members accounting for about a fifth of the country's total foreign trade, has accused the U.S. of trying to interfere in Germany's foreign affairs. The Kremlin is confident that Nord Stream 2 will not make Germany dependent on Russian Federation.

"The question is what happens to Germany's gas imports when the Netherlands stops exporting its gas".
"As for Germany's dependence (on Russia) as a major gas buyer we can not agree with this premise", Peskov told reporters on a conference call.
"As far as, say, the organization of various attacks on this commercial project, we said earlier that we thought it was a manifestation of unfair competition", he added.
"A "and the stream-2" is a tool in the hands of the Kremlin of waging a hybrid war". In other words, if the Netherlands is out of the picture, it's quite likely that LNG will enter anyway.
US President Donald Trump accused Germany on Wednesday of being a "captive" of Russian Federation due to its energy reliance. He said he also mentioned tripartite talks [on gas - EU-RF-Ukraine], which they will hold.
