Melania Trump is known to the United States Secret Service on the campaign trail as 'Muse,' DailyMail.com can reveal.

Her husband, the Republican presidential nominee, has been known to earpiece-wearing agents as 'Mogul' since the Service assigned him a traveling protective detail last November.

But Melania didn't get a code name right away because she wasn't a 'protectee' who traveled with him.

Trump's adult children likely won't get Secret Service protection. Young son Barron, 10, is a different story.

Now that the primaries are over and Mrs. Trump is a campaign fixture, the name 'Muse' is crackling from agent to agent every time she steps on or off the family's private Boeing 757, according to two sources with knowledge of the Trump family's security routine..

THE EAGLE HAS LANDED: SECRET SERVICE CODE NAMES Hillary Clinton: Evergreen Bill Clinton: Eagle Bernie Sanders: Intrepid Donald Trump: Mogul Michelle Obama: Renaissance Barack Obama: Renegade George W Bush: Trailblazer George HW Bush: Timberwolf Ronald Reagan: Rawhide Jimmy Carter: Deacon Richard Nixon: Searchlight Advertisement

Pence and his wife have code names too: 'Hoosier' and 'Hummingbird'.

Like Mogul and Muse, married couples' code names – and those of immediate family members – share a first letter.

Protectees are typically presented with a short list of options always words that can be easily understood by people who speak a variety of languages.

They ultimately get to choose from the options presented to them.

On the Democratic side of the election battle, Hillary Clinton has retained the secret service name 'Evergreen' since the 1992 presidential campaign where husband Bill – known as 'Eagle' – first ran for the White House.

Chelsea Clinton was dubbed 'Energy.'

First families retain their protective details for life at taxpayer expense.

So President Barack Obama will be known as 'Renegade,' and first lady Michelle Obama as 'Renaissance,' for decades to come.
