The Democratic political action committee End Citizens United is buying about $250,000 worth of advertisements in support of Conor Lamb , the Democratic candidate in the special election for Pennsylvanias vacant 18th District.

The ad buy will include digital video ads and a 30-second television spot attacking Republican Rick Saccone for reportedly questionable use of his expense account as a state representative.

Rick Saccone, promised no legislative perks in Harrisburg called them lavish, then gobbled them up, spending $435,000 taxpayer dollars on himself, a narrator in the TV ad, Clean House, intones as black ink splashes a white canvas.

The ad is drawn from a report in The Intercept detailing Saccones liberal use of his taxpayer-funded expense account since his 2010 election to the state House. Saccone, who won during the Tea Party wave, still touts his fiscally conservative bona fides.

The ad notes that Lamb, by contrast, has refused to take campaign donations from corporate PACs.

Were committed to making sure voters know Lambs record of integrity and Saccones history of exploiting taxpayers, said End Citizens United President Tiffany Muller in a statement about the ad.

The TV ad is due to appear on Monday and continue through March 4. The digital ads, which address similar themes, begin Friday and will continue through March 13, the day of the special election.
