Former Congressman Aaron Schock has spent more than $1 million from his campaign account over the past three months to pay for lawyers as federal authorities investigate his use of political and taxpayer funds.

A campaign finance report released Wednesday by the Federal Election Commission also shows the Peoria Republican spent thousands of dollars on fundraising trips and events in the months after resigning, even as he was refunding money to donors and selling off campaign vehicles.

Schock resigned in March amid mounting scrutiny of his spending, including a redecoration of his office in the style of TV’s “Downton Abbey.” A federal grand jury is investigating.

Among media reports were Associated Press investigations of real estate deals, air travel and entertainment, including trips and events he documented on social media accounts.
