Documents reviewed by the AP show the Paxtons hold mortgages on three homes — one in suburban Dallas, two in Austin — that are each listed as their primary residence. The designation comes with a considerable financial upside.

Texas Attorney General Ken Paxton and his now-estranged wife, State Senator Angela Paxton, declared multiple homes as their primary residences when applying for home loans, raising questions among experts about mortgage fraud, according to new reports.

The attorney general of Texas, who is challenging Senator John Cornyn, could have secured favorable mortgage rates, and may have violated the law if he knowingly falsified loan documents.
