On January 1, 2026, every sheriff in Texas with jurisdiction over a county of 100,000 or more people became, by law, a federal immigration enforcement agent. Senate Bill 8, signed by Governor Abbott in June 2025, requires these counties to enter 287(g) agreements with Immigration and Customs Enforcement — or face legal action from the Texas Attorney General by December 1, 2026.

The law's sponsors described it as a public safety necessity. But a closer look at who wrote the policy, who funded the advocacy, and who profits from the outcome tells a different story — one about how anonymous money buys state legislation and how think tanks convert donor interests into government mandates without ever registering as lobbyists.

The Money Behind the Mandate

The Texas Public Policy Foundation, Austin's most influential conservative think tank, was among the leading advocates for SB 8. TPPF testified in favor of the bill, provided policy research supporting mandatory 287(g) participation, and coordinated with the Houston Police Officers' Union to present a united enforcement front during legislative hearings.

TPPF is a 501(c)(3) nonprofit organization. It is not required by law to disclose its donors. But investigative reporting by the Texas Observer and filings reviewed by OpenSecrets reveal a donor base that raises serious questions about whose interests the foundation actually serves.

Among TPPF's documented funders: Koch Industries, ExxonMobil, Chevron, and — critically — the GEO Group, one of the two largest private prison and detention facility operators in the United States. According to the GEO Group's 2025 annual report, the company operates 11 ICE detention facilities across the southern United States, including three in Texas, with a combined capacity exceeding 14,000 beds. In fiscal year 2025, GEO Group reported $2.4 billion in revenue, with approximately 45% derived from federal immigration detention contracts, according to the company's SEC filings.

The financial logic is not subtle. More 287(g) agreements mean more immigration detainers. More detainers mean more bodies in detention facilities. More bodies mean more revenue for the companies that operate those facilities. And one of those companies funds the think tank that wrote the policy justification for the law that creates those detainers.

TPPF has not disclosed the amount of GEO Group's contributions. Neither entity responded to requests for comment.

What SB 8 Actually Requires

The law mandates that counties with populations over 100,000 enter into 287(g) Memorandums of Agreement with ICE. Under these agreements, designated sheriff's deputies receive federal training and are authorized to perform immigration enforcement functions — interviewing detained individuals about their immigration status, issuing detainers, and initiating removal proceedings.

According to ICE's own data, as of April 13, 2026, the agency has signed 1,651 287(g) agreements nationwide, covering 39 states and two U.S. territories. Texas entered the year with 299 active agreements across 186 counties — already the largest state footprint in the program.

SB 8 expands this further. The law requires at least one 287(g)-certified jailer for every 400 beds in county jails. The Texas Legislative Budget Board estimated that approximately 306 additional jailers would need federal certification to meet this threshold statewide.

The cost? The American Immigration Council has documented that initial-year 287(g) program costs in comparable counties range from $4.8 million to $5.3 million. Mecklenburg County, North Carolina spent $5.3 million in its first year of operation, according to a 2010 federal audit. Alamance County spent $4.8 million.

Texas lawmakers addressed the cost concern with a grant program administered by the Texas Comptroller, offering between $80,000 and $140,000 per county depending on population size. For a county facing $5 million in first-year costs, that grant covers roughly 2% of the bill.

Who Pays, Who Profits

The gap between the state grant and the actual cost is an unfunded mandate — a term that usually sends conservative lawmakers into orbit. When the federal government imposes costs on states without funding, Texas politicians call it tyranny. When the Texas Legislature imposes costs on counties without funding, the same politicians call it public safety.

The sheriffs who must comply didn't ask for this. During legislative hearings on SB 8, the Texas Sheriffs' Association expressed concerns about training costs, personnel diversion, and the legal liability created by deputizing county officers as immigration agents. Multiple sheriffs from border counties — the very jurisdictions the law's supporters claim to be protecting — testified that the mandate would pull deputies away from criminal investigations and community policing.

"We're being told to train officers for federal work with state money that doesn't cover the cost," one South Texas sheriff told the Texas Tribune during floor debate in May 2025. "And the federal government isn't paying either."

Meanwhile, the organizations that lobbied for SB 8 face no costs at all. TPPF's role in the process — researching, testifying, providing model language — doesn't require registering as a lobbyist under Texas law. The Center for Public Integrity has documented that model legislation written by think tanks accounts for a significant share of state legislative output nationwide. Lawmakers receive fully formed bills, insert state-specific terms, and introduce them under their own names. The practice requires no lobbying registration, no campaign finance reporting, and no disclosure of who funded the drafting.

The Accountability Gap

This is the structure that should concern every taxpayer, regardless of their position on immigration: anonymous donors fund a nonprofit think tank. The think tank writes policy language that benefits its donors. State legislators introduce the language as their own bill. The bill passes with no public accounting of who drafted it or who paid for the drafting. County governments absorb the unfunded cost. Private corporations collect the revenue.

At no point in this chain does any actor face a disclosure requirement. TPPF doesn't disclose its donors. The GEO Group doesn't disclose its contributions to specific nonprofits beyond what SEC filings require. The legislators who introduced SB 8 don't disclose who provided the model language. And the Texas Attorney General's office, which will enforce compliance, doesn't investigate the funding trail behind the laws it enforces.

The result is a system in which public policy is functionally privatized. The public pays the costs — in county budgets, in diverted law enforcement resources, in the civil liberties implications of turning local police into federal agents. The private beneficiaries collect the profits. And the organizations that engineer the transaction operate in complete anonymity.

What Comes Next

Twenty-three Texas counties with populations over 100,000 have not yet signed 287(g) agreements, according to ICE data. They have until December 1, 2026 to comply or face legal action from the Attorney General.

Several of these counties — including Travis County (Austin), Harris County (Houston), and Bexar County (San Antonio) — have Democratic county leadership and have resisted immigration enforcement cooperation for years. The coming months will test whether SB 8's mandate survives legal challenge on Tenth Amendment grounds, whether the unfunded mandate argument gains traction with conservative judges, and whether the public follows the money from the think tank to the detention facility.

The question isn't whether Texas should enforce immigration law. The question is whether voters have a right to know who wrote the laws their sheriffs are forced to follow — and who profits when they do.
