Commenting on the Monday's meeting between Russian President Vladimir Putin and his USA counterpart Donald Trump, he recalled that the parties discussed the necessity to decide on the future of the Strategic Arms Reduction Treaty (New START), which expires in 2021.
USA intelligence agencies concluded past year that the Russian government interfered in the 2016 election campaign and sought to tilt the vote in Trump's favor, which Moscow has denied.
"The sentence should have been: "I don't see any reason why I wouldn't" or "why it wouldn't be Russia".
"There are a lot of us who fully understand what happened in 2016 and it really better not happen again in 2018", McConnell said.
Trump's brief comment and Sanders' explanation were the latest statements in a week in which he's clarified his beliefs on Russian meddling multiple times, starting Monday at a summit with Putin in Helsinki, Finland.
Trump says: "I let him know we can't have this".
Jackson then followed up: "But why should this president have any credibility to Americans in what he says if in fact 24 hours later or in this case three hours later the White House comes out and says 'just kidding?'"
President Trump said he accepted his intelligence services' assessment that Russian Federation had interfered.
The White House said Wednesday that Russian Federation continues to pose a danger to the USA electoral system, just hours after President Donald Trump appeared to dismiss the threat.
President Vladimir Putin's offer to help the US investigate alleged Russian election meddling, hailed as an "incredible" gesture by Donald Trump, included the same allegations made by a Kremlin-linked lawyer at a controversial 2016 meeting with top campaign officials of the future president.

US President Donald Trump has lashed out at "haters" who condemned his meeting with Russia's president.
"So certainly as the leader of a country you would have to hold him responsible, yes".
Sanders called the legislation a "hypothetical" and declined to say whether the president would back it.
Republican Senator Bob Corker, chairman of the Senate Foreign Relations Committee, said congressional leaders were searching for the most effective response.
An exchange between President Trump and a reporter Wednesday during a Cabinet meeting has sparked confusion about where Mr. Trump stands on whether Russian Federation is continuing to target the United States.
Asked why Americans should defend North Atlantic Treaty Organisation member Montenegro from attack, Trump said, "I've asked the same question". Steve Daines (R-Mont.) said Wednesday, even though Trump had cast doubt on that intelligence the same day.
"I have great confidence in my intelligence people, but I will tell you that President Putin was extremely strong and powerful in his denial today".
