The Texas Democratic Party wants the Travis County District Attorney’s Office to investigate Lt. Gov. Dan Patrick after he sent unsolicited applications to vote by mail to potential voters.

Patrick sent applications to voters leading up to the March 1 Republican primary, including in Tarrant County where the Star-Telegram reported that an Edgecliff Village resident got one of the applications accompanied by a letter encouraging those over 65 to use the voting method. The letter contained the official seal of Patrick’s office and the return envelope for the application was addressed to the Texas Secretary of State’s Office.

The Texas Democratic Party alleged in a letter Friday to Travis County District Attorney José Garza that Patrick violated Texas election law. Patrick supported a new state law that includes a provision making it a state jail felony for a “public official or election official” to send applications to voters who didn’t request one. Under the law that went into effect Dec. 2, candidates and political parties are allowed to send the forms.

“The second-highest official, our state’s Lieutenant Governor, Dan Patrick has flagrantly violated S.B.1 (a law he championed last year) by illegally sending unsolicited vote-by-mail applications to voters across Texas and using his official seal and title to do so,” the letter from Texas Democratic Party Chairman Gilberto Hinojosa reads. “Left unchecked, the Lieutenant Governor’s actions create two sets of rules: one for Democrats (who must comply with every provision of S.B. 1) and one for Republicans (who can pick and choose which provisions of S.B. 1 apply to them).”

Hinojosa continues to ask Garza to “investigate his actions and to ensure that he will face full accountability under the Law.”

Patrick’s office and campaign did not immediately return requests for comment.

In the letter, the party raises concerns about the return envelope being addressed to the Texas Secretary of State and the letter containing Patrick’s seal. The letter’s envelope includes an address for Blakemore & Associates, which does campaign consulting for Patrick. Texas Democrats argue the law was violated regardless of whether the letter was funded by a campaign “by affixing the official seal of his office and his signature (with the signature line Dan Patrick/Lieutenant Governor) on a mailer containing mail ballot applications.”

“Dan Patrick intended for recipients of the mailer to think it was an official letter from his office,” Texas Democrats’ letter reads.

The return address being marked to the state not individual counties’ early voting clerk resulted in delays for thousands of submitted applications, according to The Texas Tribune, which reported that the letters were also received by voters in central Texas and Houston.

The Travis County District Attorney’s office confirmed they received a complaint, but declined to comment further.

The portion of the law related to sending unsolicited applications to vote by mail is the subject of pending litigation.
