Clinton also spoke with Kristof about Russia's suspected attempts to interfere with the election and James Comey's announcement 11 days before the election that the FBI would reopen its investigation into her use of a private email server during her time as Secretary of State. She pointed that during the administration of former US President Barack Obama, she had advocated for a no-fly zone in Syria, but it was opposed by Obama.
Her appearance at the Women In The World Summit is the latest in a string of public appearances for Mrs Clinton in the past few weeks. "People have asked me 'Why do you think he did that to you?'" Clinton said.
Clinton's comments came during her remarks at the Women in the World Summit on Thursday. "As an American, I'm pretty anxious".
"I am deeply concerned about what went on with Russia", Clinton said.
The two-time presidential contender soon interjected: "How much time do we have?"
Clinton, who called her loss "devastating", said she'll chronicle her defeat in excruciating detail in her forthcoming book.
Pressed by columnist Nicholas Kristof of the New York Times, Clinton said she has struggled to explain her defeat, including the fact that 53% of white women voted for Trump.
"I don't know that there is one answer", she told the Women in the World Summit in NY when asked why she thought she lost the white women's vote to a Republican who had boasted of groping women. She said that Republicans should also be concerned of what Russian Federation did. I don't know that any of them had ever even read the bill - read the law, understood how it worked. "Assad choked out the lives of helpless men, women, and children", the president said.
The 69-year-old is now slowly emerging from post-election seclusion to make speeches, promote young people and to encourage more women to get involved in politics.
In the immediate aftermath of her loss to Trump in November, the two-time presidential candidate largely stayed away from the limelight.
Clinton singled out the Russian hacking that led to Wikileaks' release of Democratic National Convention leadership emails, saying it "should give chills to anyone who cares about democracy".
