Newtown (AP) — Some residents in Newtown, Conn., say they're outraged at receiving robocalls from the National Rifle Association only three months after the Sandy Hook Elementary School shootings.

Town residents say the automated calls from the NRA began last week and urge people to tell their state legislators to oppose gun control proposals. Lawmakers are debating whether to ban military-style assault weapons, prohibit high-capacity ammunition magazines and other measures in response to the school shootings.

Dan O'Donnell lives in the Sandy Hook section of Newtown and told WVIT-TV that the robocalls are "ridiculous and insensitive."

Messages seeking comment were left with the NRA, which like other nonprofit groups is allowed to make robocalls under federal law.

A gunman killed 20 first-graders, six educators and himself in December after shooting his mother to death.
