Moment of silence marks week since Newtown tragedy Last Updated 9:30 a.m. Moments of silence were observed across the nation Friday morning, one week since the mass school shooting in Newtown. At 9:30 a.m. local time this morning - exactly a week since Adam Lanza entered Sandy Hook Elementary School - bell towers across Connecticut chimed 26 times to honor each of the victims. Similar observances are being nationwide, at 9:30 a.m. local time - exactly a week after the shooting occurred - in memory of the victims. Gov. Dannel Malloy has also asked people across Connecticut to observe a moment of silence. The White House has said President Barack Obama will privately observe the moment of silence. Newtown and environs weathered a fourth day of funerals Thursday as mourners laid to rest Catherine Hubbard, Benjamin Wheeler, Jesse Lewis and Allison Wyatt, all 6 years old; and Grace McDonnell, 7. A service was held in Katonah, N.Y., for teacher Anne Marie Murphy, 52, who authorities believe helped shield some of her students from the rain of bullets. Roman Catholic Cardinal Timothy Dolan compared her to Jesus. A bell tolled Thursday at Newtown's St. Rose of Lima Roman Catholic Church at the funeral for Catherine, who her family said would be remembered for her passion for animals and her constant smile. Trinity Episcopal church on Main Street was filled to capacity for the funeral for Benjamin, described as a budding musician and Beatles fan. His service included a rendition of "Here Comes The Sun." In downtown Danbury, mourners filed into the ornate white-pillared First Congregational Church for a memorial service for 30-year-old teacher Lauren Rousseau. Friends wept at the altar as they remembered the spirited, hardworking, sunny-natured woman who brightened their lives with silliness and gave them all nicknames. U.S. Attorney General Eric Holder was one of the people to visit Newtown on Thursday, stopping by a firehouse. The Obama administration will push to tighten gun laws in response to the shooting, Vice President Joe Biden said Thursday, and Speaker John Boehner said the GOP-controlled House would consider the proposals. Biden, who is overseeing the administration's response to Friday's shooting, said he and Obama are "absolutely committed" to curbing gun violence in the United States. "Even if we can only save one life, we have to take action," he said. Gun-control measures have faced fierce resistance in Congress for years, but that may be changing because of the events in Connecticut, which shocked the nation. After the shooting, Mr. Obama signaled for the first time that he's willing to spend significant political capital on the issue. Some prominent gun-rights advocates on Capitol Hill - Democrats and Republicans alike - have expressed willingness to consider new measures.
