(Minneapolis, MN) -- Earlier this month U.S. Representative Ihlan Omar was fined for campaign finance violations. Now Minnesota campaign finance officials say Omar filed joint income tax returns with her current husband in 2014 and 2015, but they weren't married yet. She was actually married to another man at the time. A statement from Omar's campaign says all tax filings are compliant with the applicable tax laws. Experts say when a taxpayer incorrectly files a return as "married filing jointly," it usually isn't considered to be a criminal matter. If they correct it, no further steps are taken.
