State BN chairman Teng Chang Yeow is unperturbed over calls for the Public Accounts Committee (PAC) to investigate if 1MDB funds were used to pay for Korean superstar Psy's performance at BN’s 2013 Chinese New Year open house in Penang.

“Let PAC probe the matter then,” was his brief reply when asked to respond on the matter, which was raised by DAP parliamentary leader Lim Kit Siang in a statement yesterday.

“Kit Siang should instruct his MPs in PAC to ask about the 1MDB,” he added.
