According to data for Responsive Politics by 2016, 99 percent of the National Rifle Association's $1 million in political contributions went to Republican congressional candidates.
In 2016, the NRA, which is registered as a nonprofit, spent $140 million on legislative programs and public affairs. Of the $140 million, figure $30 million went to Donald Trump's presidential campaign and at least $20 million more to GOP Senate candidates.
Much of that funding came in the form of "dark money" disbursed by the NRA's Institute for Legislative Action, a social welfare organization that is not required to disclose its donors.
If you think senators and representatives are working on your behalf, think again. To find out who they are really working for just follow the money.
