WASHINGTON — Senate Republicans backed by a small band of rural-state Democrats scuttled the most far-reaching gun control legislation in two decades Wednesday, rejecting tighter background checks for buyers and a ban on assault weapons as they spurned pleas from families of victims of last winter's school massacre in Newtown, Conn.
"This effort isn't over," President Barack Obama vowed at the White House moments after the defeat on one of his top domestic priorities. Surrounded by Newtown relatives, he said opponents of the legislation in both parties "caved to the pressure" of special interests.
A ban on high-capacity ammunition magazines also fell in a series of showdown votes four months after a gunman killed 20 elementary school children and six staff members at Sandy Hook Elementary.
A bid to loosen restrictions on concealed weapons carried across state lines was rejected, as well.
That last vote marked a rare defeat for the National Rifle Association on a day it generally triumphed over Obama, gun control advocates and many of the individuals whose lives have been affected by mass shootings in Connecticut and elsewhere.
Some of them watched from the spectator galleries above the Senate floor. "Shame on you," shouted one, Patricia Maisch, who was present two years ago when a gunman in Tucson, Ariz., killed six and wounded 13 others, including former Rep. Gabrielle Giffords.
Vice President Joe Biden gaveled the Senate back into order after the breach of decorum.
Gun control advocates, including Obama, had voiced high hopes for significant action after the Newtown shootings. But the lineup of possible legislation gradually dwindled to a focus on background checks, and in the end even that could not win Senate passage. Chances in the Republican-controlled House had seemed even slimmer.
By agreement of Senate leaders, a 60-vote majority was required for approval of any of the provisions brought to a vote.
