Former Florida Gov. Jeb Bush lashed out at Rep. Debbie Wasserman Schultz, D-Fla., amid an information technology procurement scandal involving one of her former staffers.

"The incompetence and terrible judgment displayed by Debbie Wasserman Schultz and House Democrats is jarring," Bush tweeted Saturday, with a link to a Wall Street Journal opinion piece detailing the controversy surrounding IT aide Imran Awan.

Awan was arrested at Dulles International Airport in July on bank fraud charges while allegedly trying to the flee the U.S. for his native Pakistan with his wife and children.

Earlier, Awan had been one of the subjects of a House staffer investigation launched in May to probe allegations of over-charging for federal IT equipment and breaches of security.

He was dismissed from his post in Wasserman Schultz's office only after the arrest and his old boss, the former Democratic National Committee chair, has since defended her decision to keep him on her payroll, despite a ban placed on him by Capitol Hill security.

"I believe that I did the right thing, and I would do it again," Wasserman Schultz told the Sun Sentinel Thursday. "There are times when you can't be afraid to stand alone, and you have to stand up for what's right."
