Democratic presidential nominee Hillary Clinton is stepping up her outreach to Republican voters with a new ad released Saturday highlighting GOP critics of Donald Trump.

The 30-second spot, featuring clips of prominent current and former Republican elected officials saying they can’t vote for Trump and calling him unqualified for the presidency, comes as Clinton seeks to make inroads with traditional GOP voters who are uncomfortable with the party’s bombastic nominee. In recent weeks Clinton has aggressively courted noted Republican foreign policy hands fearful of a Trump presidency, meeting with several GOP national security veterans Friday in New York City.

Last month her campaign launched the “Together for America” campaign, which features prominent Republicans, including many former Bush administration officials, working on behalf on Clinton. The national campaign is being supplemented by state-specific efforts to highlight Republicans who are crossing the aisle this November.

Reaching out to GOP voters is an imperative for Clinton, given Trump’s strong command over white working-class voters, including many who used to vote for the Democratic ticket.

According to the Clinton campaign, the ad will be rotated into its existing buys in Florida, Iowa, North Carolina, Nevada, Ohio, Pennsylvania and the Omaha media market—latter, where one Electoral College vote is at stake in the swing district.
