HB 626 grants specific federal law enforcement officers limited state law enforcement authority in Texas. Under the amendment to Article 2A.002(a) of the Code of Criminal Procedure, federal agents such as FBI special agents, DEA agents, and others are authorized to exercise powers of arrest, search, and seizure for felony offenses under Texas law. The bill includes additional roles, such as federal air marshals and Department of Defense police officers, in the list of federal personnel eligible for this authority. This measure ensures better coordination between state and federal law enforcement agencies, particularly for addressing interstate or complex criminal activity​.
