NEWTOWN, Conn. — Activists from the Connecticut town where 26 people were fatally shot last December are headed to Washington to again lobby for gun control, a day after 12 people were killed in a shooting rampage in the capital.

About 50 members of the Newtown Action Alliance left for Washington on Tuesday. Their first stop is to be a hearing by U.S. Sen. Dick Durbin, D-Ill., on Florida’s “Stand Your Ground” law.

David Ackert, the group’s founder, told the Hearst Connecticut Media Group that the shootings at the Washington Navy Yard on Monday bring back “terrible feelings.”

The group will ask Congress to require background checks for gun buyers.

Several parents of children killed at the Sandy Hook Elementary School on Dec. 14 lobbied Congress earlier this year for legislation that ultimately failed.
