Republican Rep. Aaron Schock of Illinois says he's resigning his House seat amid questions about his spending.
In a statement on Tuesday, Schock said he would step down effective March 31.
Schock, a four-term lawmaker, said he was taking the step with a "heavy heart." He said that questions about irregularities in his campaign finance and congressional spending accounts over the past six weeks have proven to be a "great distraction" and have made it too difficult for him to serve.
