Over the long Labor Day weekend, Democratic officials defended Vice President Kamala Harris from criticisms that she has been flip-flopping on various policy positions.

"I think it's a sign of a good leader, that they learn and evolve over time," Colorado Gov. Jared Polis told ABC News' "This Week" on Sunday. 

"Most voters recognize that as you get more information, as you get more experience, perhaps as you hold a different job… that there would be a natural evolution," echoed Rep. Brendan Boyle, D-Pa., during a Labor Day appearance on CNN. 

Meanwhile, Rep. Ro Khanna, D-Calif., took a different approach when he appeared on NBC News' "Meet The Press" over the weekend, describing her as a "progressive who [is] pragmatic" and one who is "consistent" in her policy approach.

During her first interview as the Democratic nominee on Thursday, Harris insisted she would "enforce" the law against illegal border crossings, something Harris indicated she was against while running her 2019 campaign to become president.

Harris also argued that she made it clear as the vice presidential nominee in 2020 that she does not wish to ban fracking, despite indicating as a presidential nominee in 2019 that she was "in favor of banning fracking" on federal land.

"This idea that she hasn't been consistent — I mean what about Donald Trump's flip-flops? What about his flip-flops on abortion?" Khanna questioned Sunday. "I think the vice president is consistent on the position on fracking. It's exactly how Joe Biden ran." 

On health care, campaign officials have said Harris does not support "Medicare-for-all." However, Harris has yet to share publicly that she is not in favor of a single-payer health care system after indicating during a 2019 debate that she would "abolish" private health care in favor of a "government-run plan." Fox News Digital reached out to the Harris campaign for clarity on Harris' position when it comes to health care, but did not receive a response. 

"I ran against her as a co-chair of Bernie Sanders' campaign — she was not for ‘Medicare-for-all’ in that 2020 primary," Khanna said.

Polis and Boyle, meanwhile, acknowledged Harris' changing positions but argued they were signs of good leadership. 

"Whether it's a move to the middle, the left, the right, it's really about what works. Kamala Harris is a pragmatic leader who looks at data and science and makes the best decisions she can," Polis said.

"I do not have 100% of the same positions today that I first had 15 years ago when I was first elected to office," Boyle told CNN in reference to Harris' stance on fracking. "That’s part of growing. I think that’s natural. The bottom line is, did you ultimately arrive at the position that is right on policy, and in the case of Kamala Harris, she did."

Boyle also charged Trump with being far more inconsistent on his policy positions than Harris. "There just is no comparison between Kamala Harris and the constant, unending flip-flops, on most issues, of Donald Trump," he said.
