IIRC, only for public figures.
The bar is far lower for private figures btw. A lot of libel/slander that would pass for public figures (ie: Politicians) are absolutely illegal and would be charged if levied against private figures instead (such as me, or the Sandy Hook victims)

Hmm... I think the bigger issue here is whether the suit would be enough reputational damage to even get to damages. IIRC, there's minimum amounts of damage done before any suit is even considered (me lawyering up would cost more than the reputational damage in that case, so it just wouldn't be worth it).
The bar is set at a certain level of damages that I expect to get awarded (and courts also reject any case where the damages are too low). This is more due to pragmatism / the innate inefficiencies of court cases that make it less likely for all cases to be considered... rather than what is strictly legal or illegal.
IE: Even if we were to make it easier to sue for smaller amounts of reputational damage, no one would do it because of the high costs of lawyers in general (and high costs of a full court case).
