AUSTIN, Texas (AP) — A federal complaint against U.S. Rep. Steve Stockman claims he exposed donors' credit card numbers on an unsecure website.
Stockman is challenging incumbent John Cornyn for the Republican U.S. senate nomination in Tuesday's Texas primary.
But his campaign has been dogged by accusations of ethics violations, and leading Texas tea party activists have formally disavowed Stockman.
On Monday, another longshot Republican challenging Cornyn, businessman Dwayne Stovall, announced he'd filed Federal Election Commission complaints against Stockman.
Stovall alleges Stockman's campaign had improper contact with an outside political group, the Center for the American Future. It was founded by a fired former Stockman staffer.
Stovall also says visitors to an unsecure Center for the American Future website can see the names, credit card numbers and billing information of donors to Stockman's campaign.
