The service said that it is leading operations it is conducting alongside U.S. Customs and Border Protection and the Department of War under U.S. Northern Command to advance Trump’s border priorities. 

"U.S. Coast Guard is the best in the world at tactical boat operations and maritime interdiction at sea, along our coasts, and in riverine environments," Adm. Kevin Lunday, acting commandant of the Coast Guard, said in a Monday statement. "Through Operation River Wall, the Coast Guard is controlling the U.S. southern border along the Rio Grande River in eastern Texas."

The Coast Guard has launched several high-profile operations in recent months. For example, the service kicked off Operation Pacific Viper in August — a joint effort between the Coast Guard and Navy aimed at countering the influx of illegal drugs to the U.S. as part of Trump’s larger effort to crack down on drug cartels.

So far, the Coast Guard has confiscated 100,000 pounds of cocaine in the Eastern Pacific Ocean since August, averaging 1,600 pounds of cocaine daily, according to the service.
