I googled it because I was curious... As best I can tell they are still together?

“The endorsement that I made years ago with Biden was one I thought was the best decision for me at that time,” he told Will Cain on Fox News in an interview posted online Friday. “I thought, ‘I’m in this position where I have some influence and I felt it was my job then to exercise my influence [and] share: This is who I’m going to endorse.’ I’m not going to do that. I was then, the most followed man in the world, and am today, and I appreciate that … but what that caused was something that tears me up in my guts — which is division. That got me. I didn’t realize that then, I just felt like there was a lot of unrest and I’d like things to calm down.”

He continued, “The takeaway after that was it caused an incredible amount of division. I realize now going into this election, I will not do that. My goal is to bring this country together. I believe in that. There will be no endorsement. At this level of influence, I will keep my politics to myself. It is between me and the ballot box. But I will tell you this: Like a lot of us out there, not trusting of all politicians, I do trust the American people and whoever they vote for that is my president and who I will support 100 percent.”

Asked if he was happy with the state of America right now, Johnson replied, “No.”

“Today’s cancel culture, woke culture, division, etcetera — that really bugs me,” he added. “In the spirit of that, you either succumb to that and be what other people want you to be, or you be yourself and be real … and that might make people upset and piss people off, and that’s OK.”
