Both of the 30-second ads that will run in Omaha center on Clinton’s claim that she played a key role in helping create a health insurance fund for low-income children while serving as first lady in the 1990s.

“It’s always been about kids. And when millions could not get health care, this first lady worked with Democrats and Republicans to fix it,” a narrator in one of the ads proclaims.

It is a claim that some Republicans dispute. They argue that as first lady she neither introduced the legislation nor shepherded it through Congress.

By all accounts, it was a landmark bill that currently insures about 8 million low-income children nationwide. In Nebraska, about 55,000 children were covered by the program in 2014.

The bill was introduced by the late U.S. Sen. Edward Kennedy, a Democrat, and Sen. Orrin Hatch, a Republican. They were the primary movers-and-shakers behind the bill, although several participants publicly praised Clinton for her behind-the-scenes role in winning support for the measure in the White House.
