Sen. Bernie Sanders, I-Vermont, on Monday said if he were to win both the Iowa caucuses and the New Hampshire primary early next year, suggested he has a real shot at winning the Democratic nomination for president.
"If we can win in Iowa, if we can win in New Hampshire, I think we're on our way to a national victory and one of the great political upsets in the modern history of America," Sanders said on "CBS This Morning."
"I think we have a shot to win in Iowa," said Sanders, who said he'll be spending a lot of time there and in New Hampshire over the next month or so.
A CBS News Battleground tracker poll released Sunday found Hillary Clinton is leading in Iowa, but Sanders is leading Clinton in New Hampshire by 14 percentage points.
Sanders again addressed his campaign's breach of voter data that led to the firing of its data director last week and the suspension of two others.
"What we're asking for now is a thorough investigation with the DNC," Sanders said on CBS. "We certainly want to get to the bottom of this."
At the same time, he again reiterated that it was "totally inappropriate" for the Democratic National Committee to cut off his campaign's access to the voter data.
Donald Trump, meanwhile, on Monday morning tweeted that Hillary Clinton should apologize for claiming that the Islamic State in Iraq and Syria (ISIS) is using footage of him and his remarks about Muslims to recruit terrorists. But fact-checkers have found no such videos.
"I fear that Donald Trump is doing a great disservice to our country, internationally, fanning hatred at the United States," Sanders said on CBS, adding that Trump is a "pathological liar" for repeating claims that thousands of Muslims celebrated in New Jersey right after 9/11.
Asked if Clinton should apologize to Trump, Sanders said, "I'll let Hillary Clinton deal with that."
"I think Donald Trump deserve to apologize to the American people," he said.
