The foreign minister has ridiculed USA media reports that President Donald Trump sought to hide the details of his private conversation with Vladimir Putin, as well as that POTUS is working on behalf of Russian Federation.
"It's hard for me to comment on what is happening in the US surrounding accusations that President Trump is effectively a Russian agent", Sergei Lavrov said, according to Bloomberg News.
He added that such requests reflect illegitimate meddling in the USA president's constitutional right to conduct foreign policy.
Lavrov called attacks on Trump by the media and Congress "unconstitutional" and "illegitimate", and refused to comment on actions taken by the Trump administration.
Asked whether the Kremlin had influenced the transparency of Trump's talks with Putin, he expressed disgust that US journalists were even covering the issue.
According to Lavrov, claims that Trump is a Kremlin agent undermine standards of journalism in the United States, and stated that there is a certain culture of diplomacy, talks and worldwide relations that everyone should observe.
Ushakov said Russia-U.S. relations were now at a level that "can't be worse".
He particularly scoffed at the charges levelled against Mr Trump's former national security adviser, Michael Flynn, saying that he talked to the Russian ambassador only in a bid to protect United States interests.
Washington has threatened to withdraw from the 1987 accord, accusing Moscow of violating the Treaty, which bans the two sides from deploying short- and intermediate-range, land-based missiles in Europe.
Trump's move to ease Russian Federation sanctions survives Senate vote
Congress has the power to reject any lessening of sanctions on Russian Federation , but only if it has enough votes. However, the effort fell three Senators short of the 60 needed to end debate and hold a vote on the resolution.
"Our questions why the Americans don't want to examine our proposals and get first-hand information about specific parameters of the missile were left unheard", he said.
Sergey Lavrov says that Russian Federation offered during talks in Geneva earlier this week that US experts see the missile.
US Undersecretary of State Andrea Thompson said following the talks that "the meeting was disappointing, as it is clear Russian Federation continues to be in material breach of the treaty".
Russian Federation has claimed that it caught former USA marine Paul Whelan "red-handed" as he was carrying out illegal activities in his Moscow hotel room. Paul Whelan, who also holds Canadian, British and Irish citizenship was detained in late December.
Lavrov denied claims Whelan was arrested in order to conduct a prisoner swap with the U.S.
Russian Federation is defending its detention of a U.S. Marine veteran by claiming he was "caught in the act" of spying.
Trump slammed this report as "a lot of fake news" and called the then-leaders of the Federal Bureau of Investigation who made a decision to investigate him "known scoundrels, I guess you could say dirty cops". He rejected allegations that Russian Federation was gloating in the turmoil, saying that Russian Federation is interested in seeing a "united, strong and, most importantly, independent European Union".
Sergey Lavrov says that Paul Whelan's brother is in Moscow and has been briefed about prison conditions.
