Attorney General Ken Paxton tapped his campaign funds to pay $2.3 million on legal fees related to his impeachment trial over the last six months, according to a new campaign finance report.

The report, which was published Thursday, is the first time Paxton has had to disclose his campaign spending since July. The House impeached him on abuse-of-office charges in May and the Senate acquitted him after a trial in September.

Paxton has previously said his impeachment defense cost him over $4 million. The report confirms Paxton used campaign funds to cover at least part of his defense and provides more detail as a politically charged battle plays out over impeachment costs.

In Texas, officeholders are generally allowed to use campaign money to defend themselves in legal matters that arise from their status as an elected official.

Paxton’s report shows that from July to December, he made payments to four law firms or lawyers that were known to be involved in the trial: $1.8 million to Stone Hilton, PLLC, $203,000 to Scheef & Stone LLP, $250,000 to Cogdell Law Firm PLLC and $100,000 to Anthony Buzbee, Paxton’s lead lawyer.
