Americans are “facing a deep set of challenges," she added.

But, she continued, “I believe in you. I believe in your persistence. And I believe your persistence will make all the difference. I believe your persistence will save our democracy."

One of those challenges, Warren said, is that high student loan debt across the country has limited millions of young people's opportunities.

“High student loan debt limits opportunities for millions of young people. Our country is fractured but I believe we can piece it back together if we persist,” she said.

“Life is full of unexpected challenges, things that pop up and make you wonder about reality. I mean, is Kanye really OK?” she asked. “Did someone bite Beyoncé’s face? Did the president of the United States really tweet about — let’s not talk about that.”

Warren, 68, considered a top potential Democratic challenger in 2020, has said that she is not actively considering a run for president but has raised eyebrows in recent months with statements alluding to possible political ambitions.

Earlier this year, Warren dodged a question on whether she would serve a full six years if reelected this year during an interview with NBC.

"We can't just be a party that says, 'Oh, we're paying attention about what happens every four years.' And I know there's a lot of anxiety, particularly on the Democratic side, about how we are going to deal with Donald Trump in 2020," she said in March.

"I take it as a no you're not pledging to serve your full six-year term if you win reelection?" NBC anchor Chuck Todd asked in response.

"I already told you. I have no intention of running for the United States, for president," she responded.
