U.S. Representative Aaron Schock, a Republican from Illinois, will resign from Congress after concerns arose about his use of taxpayer dollars, Politico reported on Tuesday.

Schock, 33, gained a following for posting flashy photos on social media of himself traveling, surfing and on other adventures. But he was hounded with questions after The Washington Post wrote in February about lavish decorations in his Capitol Hill office.

A spokesman for Schock did not immediately respond to a request for comment.

Concerns arose about his spending habits, with several media outlets reporting that he failed to disclose some expenditures and had to repay others after improperly using taxpayer funds.

Schock will resign as of March 31, Politico said, citing a statement from the lawmaker.
