U.S. Rep. Jesse Jackson Jr.’s campaign finances are the subject of a federal probe after the congressman allegedly improperly used campaign money to decorate his home, according to a new report. The Wall Street Journal reported Sunday night that a federal probe into the congressman centers on whether Jackson improperly used campaign money to decorate his home. The Chicago Sun-Times on Friday first reported that Jackson was under federal investigation, a probe that began before he took a leave from Congress in June to seek medical help.
