The deployment was ordered after the Trump administration signaled its intent to rename the Gulf of Mexico and moved quickly to fire the Coast Guard commandant.

The commandant of the US Coast Guard has been removed from her position over “leadership deficiencies” and “operational failures,” a Department of Homeland Security official confirmed to CNN on Tuesday.

Adm. Linda Fagan, the first woman to serve in the Coast Guard's top job, was relieved following the swearing-in ceremony for the new president.

The effort is meant to “to deter and prevent a maritime mass migration from Haiti and/or Cuba,” according to a statement.

The first woman to lead a branch of the armed forces was relieved of command within 24 hours of President Trump’s inauguration.

President Donald Trump has moved quickly to remake the Department of Homeland Security by firing the heads of the Transportation Security Administration and Coast Guard before their terms are up while eliminating all the members of a key aviation security advisory group.

Trump’s removal of Adm. Linda Fagan, who made history as the first woman to lead a U.S. military service, is the first of several potential leadership changes.

Coast Guard Commandant Adm. Linda Fagan, the first female uniformed leader of an Armed Forces branch in U.S. history, was ousted by the Trump administration with no explanation late Monday.

WASHINGTON (Reuters) - The Trump administration has fired U.S. Coast Guard Commandant Admiral Linda Lee Fagan, the first female uniformed leader of an armed forces branch, the Department of Homeland Security said on Tuesday.

Adm. Kevin Lunday, the vice commandant, is expected to fill the vacancy in an acting capacity until the Senate confirms a replacement.

The U.S. Coast Guard (USCG) started using the term “Gulf of America” to refer to the Gulf of Mexico on Tuesday, one day after President Trump signed an executive order setting in motion the process to change its official name.
