US Senate blocks gun-control legislation
'Shameful scare tactics'
But the NRA had warned members the proposal would require checks for sales and gifts between family and friends and lead to a national registry.
The NRA's assertions are "a lie. That is simply a lie, and anybody who can read knows that is not factual," Manchin, a strong gun-rights defender, said on the Senate floor on Wednesday.
Reid, a Nevada gun owner and gun-rights defender, accused the gun lobby of "shameful scare tactics" and questioned why his colleagues would reject a proposal backed by nearly 90 percent of Americans.
"We must strike a better balance between the right to defend ourselves and the right of every child in America to grow up safe from gun violence," Reid said.
The Democratic-led Senate also rejected several Republican-sponsored amendments backed by the NRA that would have expanded gun rights.
An amendment from Republican Senator Charles Grassley of Iowa would have replaced the existing gun-control bill with a plan to focus on prosecuting gun crimes, improving mental health records for gun owners and funding improved school safety measures. It was rejected on a 52-48 vote.
"Rather than restricting the rights of law-abiding Americans, we should be focusing on keeping guns out of the hands of violent criminals, which this legislation accomplishes," Texas Republican Senator Ted Cruz said of Grassley's measure.
