Donald Trump is now throwing his weight behind his intelligence agencies, a day after siding with Russia.
The US president read a statement to reporters on Wednesday morning (NZ time), saying he misspoke about election meddling.
In a press conference after meeting with Vladimir Putin Mr Trump said he didn't believe Russia had interfered in the election.
"I don't see any reason why it would be [Russian meddling]," Mr Trump said.
"I have great confidence in my intelligence people, but President Putin was incredibly strong in his denial."
Speaking to reporters about the comments Mr Trump said he never meant to use the word "would" and instead should have said "wouldn't".
"The sentence should have been: 'I don't see any reason why it wouldn't be Russia,' sort of a double negative," he said.
Mr Trump went on to say he accepted that Russia had clearly interfered in the 2016 US election.
"I accept our intelligence community's conclusion that Russia's meddling in the 2016 election took place," he said.
