I was able to fix the issue on RHEL 7.8 by updating ca-certificates.
sudo yum install -y ca-certificates

I wish there was a mechanism to promote this to some more-visible place in the forum.

I just spent several hours trying find this answer -- mostly because my various attempts at google search strings failed to pick it up. Here is the string that finally got me to this post:

"centos 7" "wget" "ERROR: cannot verify"

This easy, simple and working solution was EXACTLY what I needed. Thank you @hari28041994 for asking and thank you @vibhuti18 for answering!
