AUSTIN, Texas — Texas Gov. Greg Abbott said Wednesday that the state has formally asked the federal government to reimburse more than $10 billion spent on border security efforts under Operation Lone Star.

Abbott said Texas submitted documentation to the Homeland Security Department seeking repayment for costs tied to the border initiative, which he launched in March 2021. The operation has deployed Texas National Guard members and state troopers, built border barriers and used state resources to target illegal crossings, drug smuggling and other border-related crimes.

“For four years under Biden, Texas spent more than $10 billion of taxpayer money to secure the border,” Abbott said in a statement. “I have formally submitted Texas’ application to the Department of Homeland Security for reimbursement.”

The governor’s office said the reimbursement money was included in the federal law known as the One Big Beautiful Bill. The money is being administered through the Homeland Security Department and the Justice Department, and Abbott said Texas will also seek reimbursement from the Justice Department.

Operation Lone Star has been one of Abbott’s signature border policies and a frequent point of conflict with the Biden administration, which challenged some Texas border measures in court. Critics have also questioned the operation’s cost, legal footing and effect on migrants and border communities.

Abbott said he will work with Texas’ congressional delegation, President Donald Trump and federal agencies to recover the money. The governor’s office said Texas bore the largest share of state border security expenses eligible for reimbursement.
