After Putin suggested extending New START beyond its original timeframe, Trump referred to the treaty as one of many bad deals that had been negotiated by President Obama.

In all three, Trump reportedly touted his political accomplishments and popularity.

The news agency said Trump paused to ask aides what the treaty was, and then denounced it as favoring Russian Federation.

The Kremlin on Friday refused to comment on the leaked details of the telephone call.

Trump's presidency was already dogged by questions of legitimacy given that almost 3 million more Americans voted for his opponent, but the idea that a foreign adversary helped tip the scales in his direction raised the volume on those concerns.

"It wasn't like he didn't know what was being said", Spicer said of Trump. It referred Reuters to the official White House account issued after the January 28 call, which did not mention the discussion about New START.

It also reduces the number of deployed warheads to no more than 1,550 each - the fewest in decades. It does not limit non-deployed warheads.

Speaking after Kremlin talks with his Slovenian counterpart, Mr Putin said that Russia welcomes Mr Trump's statements about the need to restore strained Russia-US ties.

Smith said the readout of the call works against Trump's stated desire of improving relations with Russian Federation.

Only a few confidants were privy to the president's conversation with Putin yet at least two of them leaked informations that makes their boss look like an amateur. "Not good. Our government shouldn't have allowed that to happen".

The Obama Administration has become a convenient target for Kremlin anger about American foreign policy - although certain elements, such as the Iran nuclear deal, are seen in Russian Federation as beneficial. We are old. We're exhausted.

The ambassador also has sought to downplay differences on Iran, saying that "we disagree more on accents related to the nuclear agreement rather than substance". "A very bad thing".

Cardin has also called for an independent commission to investigate the US intelligence community's assessment that Russian Federation sought to sway the USA election in Trump's favor through the hacking of the Democratic National Committee and Hillary Clinton's campaign staff. "This account shows him accusing the Russians of taking advantage of us and belittles the best arms control deal we have had in years", she said.

"I think this whole notion of a grand bargain, where they are going to help us kill terrorists and fight ISIS in exchange for lifting sanctions, is a fantasy", Rubio said in response to comment from two witnesses, former NATO Supreme Allied Commander Europe Gen. Philip Breedlove, USAF (Ret), and Julianne Smith, senior fellow at the Center for New American Strategy. "And if Russian Federation helps us in the fight against ISIS [Islamic State], which is a major fight, and Islamic terrorism all over the world, that's a good thing", Trump told Fox News in an interview aired Sunday.
