On December 16 , 2012 , two days after the Sandy Hook Elementary School shooting , Senator Dianne Feinstein said she would introduce a new assault weapons ban on the first day of Congress . Five days later , on December 21 , Wayne LaPierre , chief executive of the National Rifle Association , held a news conference repeating the NRA 's opposition to additional gun laws . Feinstein and Senator Richard Blumenthal held a separate news conference in response . There , Feinstein said that it seemed to her " prudent " to register grandfathered assault weapons under the National Firearms Act ( NFA ) . A two-page bill summary on the senator 's web site also mentioned registering grandfathered assault weapons under the NFA , but the text of the bill introduced to the Senate did not include that provision
