(NewsNation) — A congressional candidate in Texas has been actively campaigning in churches, risking legal violation, The Guardian reports.

Republican candidate Mayra Flores has been campaigning in churches that feature her campaign banners. She’s potentially violating federal regulations that prohibit what the law calls “political campaign intervention,” as a condition of tax exemptions for nonprofit religious organizations.

Flores, who was endorsed in the primary by Donald Trump, is running to replace Democratic Rep. Vicente Gonzalez in south Texas’s competitive 34th district.

In recent months, Flores has appeared at events held at churches that are promoted as revivals, prayer events and luncheons, according to The Guardian.

Flores won the seat in a special election in June 2022, which turned the district red for the first time, but she lost it again to Gonzalez in that November’s midterms.
