“Make America return to the essence of who we are, the dignity of the country, the dignity of people, treating our people with dignity,” Biden said. “End this god-awful, deliberate division that’s being taken in order to — separating people to aggrandize his own power.”

Outlining his potential presidency, the former vice president stressed that unity would be one of three major prongs.

“We can’t stay fractured like we are now,” he said.

Biden weighed in on the findings of special counsel Robert Mueller’s Russia investigation, telling “Good Morning America” there was “without any question Russian interference” in the 2016 election, and said he believed it was now up to Congress to determine whether or not Trump obstructed the special counsel’s probe.

“There are elements in the report, in the second phase of the report, about seven or eight things that are left undone — it was not in his purview to investigate, so he thought,” Biden said of Mueller. The former vice president argued that Congress should — and is — attempting to tie up those loose ends, refusing to rule out impeachment based on what they find.

“If in fact they blocked the investigation,” Biden said, lawmakers “have no alternative but to go to the only other constitutional resort they have, is impeachment.”

But, he added, “my job in the meantime is to make sure he’s not back as president of the United States of America.”

He was also pressed on recent allegations from women who have said the former vice president was overly touchy with them, making them uncomfortable. Although Biden said he took responsibility for his actions and acknowledged that times have changed, he did not offer an apology.

The former vice president came under fire for his response to the allegations, which at first amounted to silence while his spokespeople issued statements. After he had posted a video on Twitter personally addressing the issue for the first time, the former vice president caught heat for appearing to poke fun at it days later in a speech to union workers.

“Some people were wondering: Do you really get it?” “GMA” anchor Robin Roberts asked of the joke.

“I really do,” Biden responded.

“Here’s the deal: I’ve always thought that part of leadership, part of politics, was listening to people, hearing them, making them feel comfortable,” he continued. “It’s my responsibility to be more sensitive to whether or not someone wants me to reassure them or wants to say hello or wants to show affection toward. And that’s my responsibility.”

Biden’s wife, Jill, defended his tactile approach to communication but said he would need to change his approach going forward.

“I think what you don’t realize is how many people approach Joe,” she said. “Men and women, looking for comfort or empathy. But going forward, I think he’s going to have to judge, be a better judge, of when people approach him, how he’s going to react. That he maybe shouldn’t approach them.”

She also said there have been situations in which a man had imposed on her personal space and made her feel uncomfortable, adding that at least one incident had been notable enough that she went home and told her husband about it.

“I just sort of stepped aside. I didn’t address it. I, like you said, I mean, things have changed. There was a time when women were afraid to speak out,” Biden said of how she addressed it. “And I can remember specifically — it was in a job interview. And so that’s where we’ve moved from, that now if that same thing happened today, I’d turn around and say, ‘What do you think you’re doing?’ So I think it’s — it’s totally different.”

Asked how he planned to stand out in a field that encompasses 20 White House hopefuls, the former vice president shot down the idea that he’s running for Barack Obama’s third term in the White House.

Biden argued for building on the progress of the Obama administration and doubled down on his embrace of the former president. Online, Biden’s campaign released a three-minute video cut with Obama’s 2017 speech awarding Biden the Presidential Medal of Freedom.

The former vice president has led nearly every national and early-state poll since before he jumped into the race Thursday and crushed his competitors in first-day fundraising totals. But while some in the Democratic establishment have eyed Biden as the most electable candidate in the expansive primary field, he’s faced questions about whether the party has shifted too far left in recent years for him to be named its standard-bearer.

Last month, Biden told reporters he was proud to be an “Obama-Biden Democrat,” which he reiterated Tuesday.

“I’m really proud of serving with Barack, with the president,” Biden said on “Good Morning America.” “But look, it’s a new time, a new day. We’re moving on to deal with the things that are within our grasp. I’ve worked my whole life: Finishing the job on equality for women. Finish the job in terms of what we’re going to do about the environment, make bold new steps forward.”

He asserted that though Trump is overseeing a booming economy, he hasn’t done enough to help “the vast majority of the working-class and middle-class people” and asked Trump voters to consider whether they’d benefited “significantly” from his signature tax law.

“They know they’re not being treated very well. This is about restoring the dignity of work,” he said, “and it’s not happening right now.”

Jill Biden interjected with some veiled criticism of the several relative political newcomers who have jumped into the 2020 race, pointing out that Biden’s experience in the White House is unmatched.

“The one thing that does differentiate you is experience,” she said. “He doesn’t need any on-the-job training. He jumps right in, he’s been vice president. So, from Day One, Joe can take everything.”
