Sen. Bernie Sanders stunned many on Sunday when he smacked down the assertion that he’s an “open border advocate.”

During a campaign event in Oskaloosa, Iowa, Sanders spoke to voters for a little over an hour about his 2020 presidential campaign and many of the policies he supports.

Towards the end of his remarks, he took a question from an audience member who asked about opening up taxpayer-funded healthcare and social security to millions of illegal aliens currently living in the United States.

After referring to the Vermont socialist as an “open borders advocate,” Sanders immediately interjected, saying, “who do you think is suggesting for opening the borders?”

“Well, you’re an activist for opening up…” the audience member continued, before Sanders cut him off again, saying, “No, I’m not.”

“I’m afraid you may be getting your information wrong,” Sanders added, holding up his hand and pointing towards the audience member.

“Ok, I apologize, thank you,” the audience member said before giving up the microphone and sitting back down.

“If you open the borders, there’s a lot of poverty in this world, and you’re going to have people from all over the world. And I don’t think that’s something that we can do at this point. Can’t do it,” Sanders said.

The room went dead silent after Sanders’ remarks, with no one clapping or making a sound.

This wasn’t the only time Sanders made headlines this weekend with his comments.

At a campaign stop in Muscatine, Iowa, on Saturday, the Vermont lawmaker voiced his support for allowing convicted felons the right to vote while serving their time in prison.

“I think that is absolutely the direction we should go,” Sanders told the audience.

“In my state, what we do is separate. You’re paying a price, you committed a crime, you’re in jail. That’s bad,” Sanders said. “But you’re still living in American society and you have a right to vote. I believe in that, yes, I do.”

Sanders appears to be the first 2020 Democratic presidential candidate who has gone on record voicing support for felons being allowed to vote while behind bars.

According to the Des Moines Register, Sen. Elizabeth Warren suggested at a “presidential forum” in Storm Lake, Iowa, over the weekend that she would not support extending voting rights to felons.

Warren, who is arguably one of the most progressive candidates in the 2020 field of at least 19 Democrats running for president, demurred and didn’t offer her support when asked if felons should be allowed to vote in prison.
