Just before Mitt Romney left the Massachusetts governor’s office and first ran for president, 11 of his top aides purchased their state-issued computer hard drives, and the Romney administration’s emails were all wiped from a server, according to interviews and records obtained by the Globe. Romney administration officials had the remaining computers in the governor’s office replaced just before Governor Deval Patrick staff showed up to take power in January 2007, according to Mark Reilly, Patrick’s chief legal counsel. Andrea Saul, a spokeswoman for the Romney campaign, said the governor’s aides did nothing wrong.
