Story highlights A narrator says Clinton is "one of the wealthiest women in politics"

The video ends by saying: "An out of touch hypocrite. She'd leave you defenseless"

It will air in Pennsylvania, Ohio, Nevada and North Carolina and at about $3 million it's the most expensive pro-Trump ad buy to date, according to an NRA spokeswoman.
