The race between Texas Sen. Ted Cruz and Rep. Beto O’Rourke got intensely personal as the Republican incumbent criticized his Democratic challenger’s mother’s business.

Cruz’s campaign released a press statement with the headline “Hypocrite Alert: Beto O’Rourke Pushes for More Taxes but Ignores Mom’s Tax Fraud,” which refers to Melissa O’Rourke’s furniture store being fined for manipulating records to avoid paying taxes.

“It is an interesting policy position given his family history of breaking tax laws while running a furniture store in El Paso,” the release said.

Ultimately the store was forced to pay $250,000 in fines, the El Paso Times reported. Melissa O’Rourke closed the store in 2017 but said at the time it was unrelated to her son’s candidacy.

“Rep. Beto O’Rourke has been campaigning on ethics in government, but he’s been hiding his mother’s conviction for tax fraud, his personal stake in her furniture company and his profiting from the company,” Cruz spokesman Emily Miller said in the news release.
