Ron Johnson, R-Wis., speaks during a committee hearing on conditions at the Southern border, on Capitol Hill in Washington. The Republican is chairman of the Senate Foreign Relations Committee's Subcommittee on Europe and Regional Security Cooperation.
Murphy said he believes 'it's important to maintain dialogue, especially during moments of tension'.
U.S. President Donald Trump said last week it would be appropriate to let Russian Federation return to the G7 group of advanced industrialized countries, telling reporters that former Democratic President Barack Obama had wanted Russian Federation out of what used to be the G8 but he thought it was "much more appropriate" to include the country.
"Johnson's groundless accusations against Russian Federation leave no doubts - he is not ready for a dialogue, but a confrontation", the embassy's statement on Twitter continued. Those latter three stops were part of the original itinerary, the staffer said. Working with Ambassador Huntsman, I had hoped direct dialogue with Russian parliamentarians could help set the stage for better future relations between our two nations.
It did not immediately comment on Murphy's comments, which came out later.
In his statement announcing he had been denied a visa to Russian Federation for next week, Johnson blasted Putin for setting his country down a path that is "a tragedy of historic proportions".
Trump acknowledged at a news conference Monday in France that he and his G7 counterparts had discussed bringing Russian Federation back into the former G8.
The Republican says his opposition to Russian aggression in Georgia and the Crimea region of Ukraine will not change, and that Russian President Vladimir Putin continues to disrespect elections and refuses to bring Russia's economy in line with the rest of the West. Police have used force to disperse the demonstrations and detained more than 2,000 people, triggering global condemnation.
In March 2014, Moscow seized control of Ukraine's Crimean Peninsula after sending in troops and staging a referendum dismissed as illegal by at least 100 countries.
Moscow denies involvement in the Donbas conflict in eastern Ukraine, where more than 13,000 people have been killed since April 2014.
Johnson noted in his statement that he has supported aggressive legislation against Russian Federation over its invasion of Ukraine.
Johnson and Murphy in March were among a group of lawmakers who introduced legislation that seeks to counter Russia's Nord Stream 2 pipeline project with sanctions.
But after a Moscow trip in June 2018, Johnson said that Congress had gone too far with punishing Russian Federation for election meddling.
The Russian embassy in the USA accused Johnson of distorting Russian foreign policy "in his usual russophobic manner" and said it believes the Wisconsin senator "is ready not for a dialogue, but a confrontation".
