"We see that there are forces in the United States that are prepared to casually sacrifice Russian-U.S. relations, to sacrifice them for their ambitions in an internal political battle in the United States".
Trump called the remark a mistake on Tuesday, telling reporters that he meant to side with US intelligence agencies, but the administration still faced questions over whether the president was sufficiently confronting Putin on issues of election interference and foreign policy.
Putin did not name names, but spoke of US politicians who put their "narrow party interests" above the best interests of the United States and were powerful enough to be able to foist their questionable "stories" on millions of Americans.
Trump has come under bipartisan fire at home for what many saw as his unsettling embrace of the Russian strongman this week in Helsinki - and his seeming disavowal of his own intelligence agencies and their assessment that Moscow meddled in the 2016 election.
In a toughly-worded speech, Putin said US-Russia ties were by "some parameters" worse than during the Cold War and took aim at the US establishment.
President Trump said: "My people came to me and some others, they said they think it's Russian Federation".
Many accused Trump of being a "traitor", saying his performance in Helsinki only deepened rumours that the Kremlin may have compromising information on him and sparked talk of new sanctions against Russian Federation.

His colleague, Labour's Paula Sherriff, said she had "important meetings" scheduled for next week and would vote against the move. And he said Britain should be "great independent actors" on the world stage, not "rule takers".
"Despite the difference in opinions (with Trump), we did agree that Russian-U.S. relations are in an extremely unsatisfactory state".
"We need a new positive agenda, aimed at working together and finding common ground", he said.
Trump later said he had misspoken and accused "some people" of hating the fact that he got along with Putin.
"It would be naive to think that problems that have been accumulating for years would be solved in a matter of hours".
Asked if he held Putin personally responsible for the meddling, Trump said "I would, because he's in charge of the country, just like I consider myself to be responsible for things that happen in this country". When Trump said he couldn't see any reason why Russian Federation "would" have been involved in the USA presidential election what he meant to say was "wouldn't".
It's a striking cover that comments on the controversy around Trump and Putin's recent summit in Helsinki, Finland.
Even some in Trump's party signalled they had had enough of his wrecking ball diplomacy and sought to take steps to box him in. "So certainly as the leader of the country you would have to hold him responsible". "The combining of faces is a different way for people to see what they couldn't see before".
