SALEM, N.H. (AP) — Former House Speaker Newt Gingrich demanded Monday that Republican presidential rival Mitt Romney tell the public more about how he operated as a venture capitalist, saying the GOP can’t have a nominee who will be vulnerable to Obama campaign charges of corporate raiding.

Gingrich said he hasn’t seen a new campaign film that will be aired by a super PAC in his behalf in South Carolina, a production that faults the former Massachusetts governor as a ruthless corporate raider whose work often led to pink slips for workers.
