WASHINGTON (AP) - Democratic presidential front-runner Hillary Rodham Clinton is making her first appearance in an advertisement funded by wealthy Republican donors tied to billionaires Charles and David Koch.

WASHINGTON (AP) Democratic presidential front-runner Hillary Rodham Clinton is making her first appearance in an advertisement funded by wealthy Republican donors tied to billionaires Charles and David Koch.

A 30-second ad aimed at Internet users in South Carolina and Florida shows headlines about veterans who have died while awaiting health care. Then it shows a recent MSNBC interview with Clinton saying of problems at the Department of Veterans Affairs, "It's not been widespread as it has been made out to be."

Text in the ad says: "Not widespread? Our veterans deserve better."

The digital ad is backed by at least $100,000 from a nonprofit group, Concerned Veterans for America, that does not identify its donors. The ad is timed to run as Clinton participates in a Democratic candidate forum in South Carolina.
