A lawyer would have to answer the question about statute of limitations.
But, this is a civil case- and I’ve seen tobacco and asbestos civil cases in the news where the act happened decades ago but the damages only occurred recently.
This sounds similar- Rush was only damaged this week from the libel.
If Rush sues, there’s no way he should ever settle. This needs to run the full course.
I saw a CNN graphic where they used Rush’s face as well as the full screen MLK quote, and attributed it to him as a direct quote.
Rush should man the torpedoes. Sink ‘em.
