When embattled Congressman Aaron Schock resigned, many said he was not out of the woods on the ethics front. Now the other shoe has dropped. A source tells the Associated Press the Justice Department has started a crminal investigation into the Peoria Republican's office and campaign expenses. His personal business dealings, including profitable real estate deals, with political donors are also under the DOJ microscope. A federal grand jury is being assembled in Springfield, and the FBI has begun issuing subpoenas to compel people close to the Republican congressman to testify. The grand jury will hear testimony in early April. The US Attorney's office in Springfield isn't commenting.
