WATCH: "Go For It": Bernie Sanders Rips Trump Over Losing Supporters

The floundering Trump campaign is slowly falling apart, and Vermont Sen. Bernie Sanders (I) says the fault lies with Donald Trump himself.

Sanders made the rounds on the Sunday news shows, delivering the dual messages that while the Trump campaign is losing support, the energy of the Harris-Walz campaign can't be denied.

Vice President Kamala Harris" should be very proud of the record of the Biden-Harris administration in taking on the greed of the pharmaceutical industry, lowering the cost of prescription drugs, and creating millions of jobs by rebuilding our crumbling infrastructure,” Sanders said on CNN’s “State of the Union.”

“We have done more in that area than any administration in history. We are working hard to combat climate change, creating jobs, doing that,” Bernie added. “So we are making some progress.”

Sanders said he has been campaigning for Harris and her running mate, Minnesota Gov. Tim Walz, across the country and is committed to getting them elected. And refused to give in to anchor Dana Bash's baiting.

“I am going to do everything that I can to see that Donald Trump is defeated and they are the next administration in this — in our country,” he said.

Over on MSNBC, Sanders mocked Trump for not being able to deliver a cohesive message to his supporters. It's no secret that Trump is his own worst enemy, but wanting to end the Affordable Care Act (mainly because people still call it Obamacare, let's be honest) is a great way to lose support, Bernie said.

"So, go for it."
