Just a couple quick feedback points:

I'd prefer if the currently selected fact text remained highlighted when the mouse is not hovered over it. That way you know what the active "Investigate >" link is referring to.

Also, for accessibility and convenience, it would be nice if you could tab through the instances of the fact text blocks.

Thanks for the feedback, the second (accessibility) should be a quick fix.

I definitely also want to address the first issue, the tricky part is coming up with a solution that also works when there are multiple assertions on one line, but I'll give it more thought.
