An independent government watchdog says Democratic Minnesota Rep. Ilhan Omar's campaign may have committed serious campaign finance fraud.

Omar's campaign spent $21,547 on travel for the E Street Group, run by Tim Mynett, whose wife is now accusing him of leaving her for Omar. Tom Anderson, who is with the conservative National Legal and Policy Center, said the travel payment may actually be Omar using campaign funds for personal use, according to the Daily Caller News Foundation.

"We believe Representative Ilhan Omar may have touched the third rail of campaign finance law: disbursing campaign funds for personal use," Anderson said. "It's a brazen act Representative Omar was caught doing before in Minnesota and all of the evidence we've seen tells us she’s probably doing it again."

Anderson's speculation comes after Beth Mynett accused her husband, Tim, of leaving her for Omar in a divorce filing. Omar and Tim are connected through the E Street Group, which Tim owns and Omar hired to advise in her run for Congress. Beth asserted in her divorce filing that her husband's "extensive travel" with Omar was likely unrelated to his work with the E Street Group.

In her divorce filing, Beth said that Tim's "more recent travel and long work hours now appear to be more related to his affair with Rep. Omar than with his actual work commitments."
