Two activist groups will launch ads Wednesday targeting embattled Republican Congressmen Tom DeLay of Texas and Bob Ney of Ohio.

The campaign focuses on the men's alleged links to a widespread congressional corruption probe of disgraced lobbyist Jack Abramoff.

The ads are being paid for by the Campaign for America's Future and Public Campaign Action Fund.

The groups are spending $115,000 on a TV broadcast on Houston stations aimed at Delay, who ives in nearby Sugar Land.

The funding also will pay for an ad on radio stations in southeastern Ohio and a billboard.

The ads will run for one week.

DeLay is awaiting trial on money laundering charges in Texas.

He says he's innocent.

The ad focusing on Ney accuses the Ohio lawmaker of accepting gifts for political favors.
