Hillary Clinton on Wednesday said she is unsure if President Trump colluded with Russia to win the 2016 election, but pointed to "interesting coincidences" between campaign associates and the foreign power that suggest otherwise.

"Do you think that the Trump campaign, with the knowledge of the now-president, colluded with Russia and stole this electioin?" NBC "Today" host Matt Lauer asked.

"Matt, I can't say that. That's what this investigation is to determine," Clinton said.

"Has it [the time since the election] led you more in the direction of collusion?" Lauer asked.

"It has suggested to me that there was certainly — we know — a plan from [Russian President Vladimir] Putin and the highest levels of the Kremlin to influence our election," Clinton said. "We know so much more than we did even when I turned the manuscripts in."

Clinton pointed to a "lot of interesting coincidences" between Trump campaign associates and the Russian government.

"I mean, you had Trump associates saying in August that, 'Oh, John Podesta's going to end up in the barrel,' " Clinton said. "Well, how would he have known that? The Russians hacked those emails — they stole them."

Clinton added the biggest reason for her loss was due to former FBI Director James Comey's reopening part of the email investigation weeks before the election.
