Gov. Nikki Haley has canceled weekend visits to swing states for GOP presidential nominee Mitt Romney to concentrate on recovery efforts after hackers stole state tax information belonging to up to 4.25 million consumers and businesses.
Haley, who endorsed the former Massachusetts governor before the S.C. primary in January was slated to visit Ohio on Saturday, said Tim Pearson, who is running her political operation.
The Buckeye State is seen as the linchpin to winning the White House.
The governor has stumped for Romney in Michigan, North Carolina, Virginia and Florida.
She also gave a prime time speech during the Republican National Convention in Tampa, Fla., and participated in GOP-response news conferences during the Democratic National Convention in Charlotte.
No decision has been made whether Haley will campaign this weekend for several state senate candidates she has endorsed, Pearson said.
Haley will hold a cabinet meeting today to figure out ways to get the word to more people about signing up for free credit-fraud monitoring. About 420,000 has signed up through Wednesday.
The breach was revealed Friday -- 16 days after the Secret Service told state officials about the hack.
