The National Rifle Association is unleashing its lobbyists on lawmakers - hoping to use its political muscle to knock down President Obama's gun control proposals.
The group is also taking its message to the airwaves - releasing an explosive new ad. The White House called the ad "repugnant and cowardly" for mentioning the President's children.
But the NRA is not backing down, it released a statement saying:
"The NRA will continue to focus on keeping our children safe and securing our schools, fixing our broken mental health system, and prosecuting violent criminals to the fullest extent of the law."
If history's any indication, the organization has been pretty successful at driving its agenda in Washington.
So how did this group become so influential?
