The head of the S.C. Democratic Party will be in Charleston today to mark the one-year anniversary of last year’s taxpayer ID hacking.

Chairman Jaime Harrison will hold a news conference at Charleston City Hall to mark the one-year anniversary of “the Haley administration’s confirmation that 6.4 million consumers and businesses had their information stolen in the Department of Revenue hacking,” the party said in a news release this morning.

The conference will address what the party said are statewide silent vigils about the breach.

Harrison will be at City Hall, 80 Broad St., at 1 p.m.
