A report from a watchdog group said the campaign committee for Congressman Aaron Schock (R-IL) reimbursed him for stays at a hotel in Greece and a luxury resort in Miami.
Schock's campaign committee reportedly paid him more than $100,000 for such expenses during the 2010 election.
The study was issued by “Citizens for Responsibility and Ethics." Director Melanie Sloan said “What Aaron Schock did crossed the line.”
The group also found 248 of 435 House members used campaign funds to benefit themselves and family members.
A federal judge struck down part of Illinois' campaign finance law.
Judge Marvin Aspen said Illinois cannot enforce contribution limits on independent political action committees. Aspen issued his ruling on March 13.
