Texas Attorney General Ken Paxton’s office is asking an appeals court to stop Harris County’s new guaranteed income program, Uplift Harris, from sending out checks to low-income residents after a judge on Thursday ruled that the program could move forward.

Paxton’s office has challenged the legality of the county’s plan to send $500 monthly payments to around 1,900 low-income households over the course of 18 months, arguing the Uplift Harris program violates the state constitution and requesting a temporary injunction to prevent the county from disbursing the first checks on April 24 as planned.
