Independent Vermont Sen. Bernie Sanders acknowledged this past weekend that President Donald Trump is doing a good job cracking down on fentanyl and securing U.S. borders.

“I think cracking down on fentanyl, making sure our borders are stronger,” Sanders said on ABC News when asked whether he thought Trump had done anything right during his time so far in office.

"Nobody thinks illegal immigration is appropriate, and I happen to think we need comprehensive immigration reform, but I don’t think it’s appropriate for people to be coming across the border illegally," said Sanders, among the most liberal lawmakers on Capitol Hill.

However, Sanders also said he disagreed with Trump's plan to conduct mass deportations in the U.S. 

“He wants to deport 20 million people who are in this country who are undocumented,” he said. “Well, you do that, you destroy the entire country.”

Sanders also returned to his argument over the past week and months that Trump, the business titans including Elon Musk whom he has nominated or appointed, and the influence of corporate money in politics is moving the country toward oligarchy, in which a small number of people have control of a country.

"Trump’s billionaire friends are not going to pick the crops in California that feed us," he said. "They’re not going to work in meatpacking houses. That’s what undocumented people are doing.”
