“After what happened here in Sandy Hook, we believe that we need to do more to curb gun violence, and Congress has not taken action,” said Po Murray, a mother of four former Sandy Hook students who is among those who presented the complaint to the State Elections Enforcement Commission.

Murray said the group believes the NRA funneled about $11,000 in so-called independent expenditures to oppose Malloy while also sending $9,000 in federal PAC money to 33 state Senate and House candidates from both political parties more than a decade ago.

“The money was transferred, and it’s illegal under the campaign finance laws in Connecticut,” Murray said.

The complaint also alleges the itemized expenditures included $4,000 to pay for office staff at NRA national headquarters in Virginia.
