COLUMBIA, S.C. (AP) — The head of South Carolina’s National Guard said Tuesday he will conduct an internal review of the Guard’s policy on social media use after Gov. Nikki Haley’s husband used Facebook to call members of the state Senate cowards for not voting on a bill favored by his wife.

Maj. Gen. Robert Livingston said he spoke with Michael Haley about the matter, and Michael Haley told the general he intended to express himself as a private citizen, not as a member of the Guard.
