HARTFORD, Conn. (AP) A legislative commission is sending along several gun-related proposals as legislative leaders continue closed-door talks, seeking to come up with a bipartisan response to the school shooting in Newtown.

Members of the General Assembly's Public Safety and Security Committee on Tuesday approved bills that would require criminal background checks for all private firearm sales and toughen the rules against carrying a loaded weapon while intoxicated, lowering the threshold for drunkenness.

The committee also voted to require local authorities to issue permits for gun shows in their communities.

Another bill that cleared the committee requires the state's Emergency Services and Public Protection commissioner to use the statewide police emergency radio network to notify all local police of a shooting involving multiple victims.

Legislative leaders are expected to continue their discussions Wednesday.

Connecticut lawmakers are considering ways to boost security measures at the state's colleges and universities, in addition to primary and secondary schools, following the deadly massacre at Sandy Hook Elementary School.

Members of the General Assembly's Higher Education Committee on Tuesday heard testimony on a bill that would require each state and independent higher education institution to submit an up-to-date security protocol plan to the state's Department of Emergency Services and Public Protection by Oct. 1.

The schools would also be required to establish trained threat assessment teams for their campuses.

Rep. Roberta Willis, the committee's co-chairman, said a bipartisan legislative task force had originally planned to review higher education security but did not have enough time. The members decided to instead focus on primary and secondary school safety measures.
