"I couldn't care less", Trump said. They also sought to determine whether Trump was deliberately working for Russian Federation or had unintentionally been influenced by Moscow.
He slammed the Times story as "the most insulting article I've ever had written and if you read the article, you'd see that they found absolutely nothing".
According to the newspaper, the meeting with Putin took place in Hamburg in July 2017, which was also attended by the then Secretary of State Rex Tillerson.
Trump's secrecy surrounding Putin "is not only unusual by historical standards, it is outrageous", said Strobe Talbott, a former deputy secretary of state now at the Brookings Institution, who participated in more than a dozen meetings between former presidents Bill Clinton and Boris Yeltsin in the 1990s.
President Donald Trump on Saturday said the idea that he ever worked for Russian Federation was "insulting", and he slammed a New York Times article regarding his potential ties to Russian Federation as "the most insulting article". You sit with the president of various countries, I do it with all countries. The publication claimed that even the classified U.S. files did not contain a single detailed record of conversations in five locations over the past two years.
The constraints that Trump imposed are part of a broader pattern by the president of shielding his communications with Putin from public scrutiny and preventing even high-ranking officials in his own administration from fully knowing what he has told one of the United States' main adversaries.
Trump disclosed classified information about a terror plot, called former Federal Bureau of Investigation director James Comey a "nut job", and said that firing Comey had removed "great pressure" on his relationship with Russian Federation.

House Judiciary Committee Chairman Jerrold Nadler said his panel "will take steps to better understand both the president's actions and the FBI's response to that behaviour" in coming weeks.
"Wow, just learned in the Failing New York Times that the corrupt former leaders of the FBI, nearly all fired or forced to leave the agency for some very bad reasons, opened up an investigation on me, for no reason & with no proof, after I fired Lyin' James Comey, a total sleaze!"
The White House press secretary, Sarah Huckabee Sanders, called the Times report "absurd" and said Comey was sacked for being "a disgraced partisan hack".
"If you ask the folks in Russian Federation, I've been tougher on Russian Federation than anybody else, any other. probably any other president, period, but certainly the last three or four presidents".
Trump has repeatedly denied any collusion.
The inquiry forced counterintelligence investigators to evaluate whether Trump was a potential threat to national security.
Mueller has indicted 33 people, including members of Russia's GRU military intelligence, and chalked up convictions against some of the president's close associates.
