Former Vice President Joe Biden, in a two-minute video released Wednesday, defended past behavior of close contact with women that has come under recent scrutiny, but also said he’s able to change.

The response from Biden, who is laying the groundwork for a potential presidential run, came a day after two more women shared stories of encounters with him that they alleged were inappropriate. Their comments followed similar complaints from two other women.

“I want to talk about gestures of support that I’ve made to women and some men that have made them uncomfortable,” Biden said, seated on a couch and speaking directly to the camera. “I’ve always tried to make a human connection that’s my responsibility, I think … it’s the way I’ve always been, it’s the way I try to show I care about them and listening.”

But despite that, Biden said, he is going to be “mindful” of people’s boundaries going forward.

“The boundaries of protecting personal space have been reset. I get it, I get it, I hear what they’re saying and I understand it,” he said.
