Texas authorities are seeking legal recourse against a controversial migrant relocation operation spearheaded by Florida Governor Ron DeSantis. The Bexar County Sheriff's Office in Texas has proposed filing criminal charges over DeSantis' orchestration of flights transferring 49 undocumented migrants from San Antonio, Texas to Martha's Vineyard, Massachusetts last year​​.

The flights, as per DeSantis, were a component of his administration's migrant relocation plan. However, the Bexar County Sheriff, Javier Salazar, raised concerns over the voluntariness of the migrants' participation, hinting they were allegedly "lured under false pretenses", according to Axios ​. Adelina Simpson, a spokesperson for the Bexar County Sheriff's Office, disclosed that both misdemeanor and felony charges of unlawful restraint have been lodged with the Bexar County District Attorney's Office for review​.

The maneuver by DeSantis, a potential 2024 presidential candidate, was part of a broader protest against President Biden's immigration policies, which has been a central issue of his political career​. Last year, he signed a law mandating companies with over 25 employees to verify the immigration status of their staff. The law also made out-of-state driver's licenses issued to undocumented immigrants invalid, inciting a travel advisory from the League of United Latin American Citizens warning individuals against visiting Florida​1​.

The situation drew attention and criticism from California Governor Gavin Newsom, who threatened to press kidnapping charges against DeSantis. This came after Florida used public funds to transport a group of asylum seekers to Sacramento without prior notice, marking the second instance in four days. Newsom referred to DeSantis as a "small, pathetic man" after the latter chartered a private jet and left 16 South American individuals outside a Sacramento church​, according to The Guardian​.

Salazar said that the charges range from "unlawful restraint, which is a state jail felony, to false imprisonment, which is a second degree felony"​. This situation has stirred an "urgent humanitarian situation," as described by officials, and has been widely criticized as a political stunt​​.
