AUSTIN (July 11, 2012)--U.S. Senate candidate Ted Cruz's campaign acknowledges Cruz missed a deadline to file his financial disclosure forms, but is also challenging Lt. Gov. David Dewhurst to explain why his office deleted past speeches from his official website.

A spokesman for the Cruz campaign said Wednesday that Cruz filed his disclosure two months late and will pay a $200 fine.

But he also pointed out that a speech that Dewhurst gave supporting a guest worker program to allow illegal workers to remain in the country was no longer available online.

Dewhurst's official spokeswoman said the lieutenant governor's office requested that all of his speeches be deleted more than a year ago.

Some links, though, were still active within the last month.

She could not explain why the order was given.

Cruz and Dewhurst are vying for the GOP nomination to the U.S. Senate seat of retiring Sen. Kay Bailey Hutchison.
