"The NRA has had a stranglehold on Congress," she added as she marched toward the NRA's unmarked office. "It's time to call them out."
The group's reach on Capitol Hill is wide as it wields its deep pockets to defeat lawmakers, many of them Democrats, who push for restrictions on gun ownership.
The NRA outspent its chief opponent by a 73-1 margin to lobby the outgoing Congress, according to the nonpartisan Sunlight Foundation, which tracks such spending. It spent more than 4,000 times its biggest opponents during the 2012 election.
In all, the group spent at least $24 million this election cycle — $16.8 million through its political action committee and nearly $7.5 million through its affiliated Institute for Legislative Action. Its chief foil, the Brady Campaign to Prevent Gun Violence, spent just $5,816.
On direct lobbying, the NRA also was mismatched. Through July 1, the NRA spent $4.4 million to lobby Congress to the Brady Campaign's $60,000.
