The US Secret Service has given presidential hopefuls Bernie Sanders, Donald Trump and Ben Carson their very own code names.

The names, which are given to presidents, their families and vice presidents were traditionally used to confuse anyone listening into the Secret Service's radio network.

Instead of saying 'the president is leaving', the secret service would use the codename instead.

Now, the Secret Service's communications network is encrypted but the tradition of codenames has been retained.

Republican candidate Donald Trump, unsurprisingly, has been given the name 'Mogul' while Bernie Sanders is 'Intrepid', which can mean someone who is courageous and fearless.

Ben Carson, who is remaining in the Republican race has been called 'Eli'.

Hillary Clinton was given the name 'Evergreen' while her husband is 'Eagle'.

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

According to CNN, Senator Sanders was given Secret Service protection two days after his loss in Iowa.

President Obama's Secret Service name is 'Renegade', while George W. Bush was called 'Trailblazer'.

His father, George H.W. Bush has the code name Timberwolf.

During his father's one term as president, George W. Bush originally had the code name Tumbler - because he kept falling down drunk.

President Reagan was known as 'Rawhide' on account of his earlier career playing cowboys in movies.

Democratic president Jimmy Carter was given the name 'Deacon' due to his strong Christian beliefs.

Richard Nixon's name was 'Searchlight', while Lyndon B Johnson was Volunteer.

Harry Truman was known as 'General' while John F Kennedy was 'Lancer'.

Senator Sanders is closing the gap on Hillary Clinton who was expected to easily win the Democratic nomination.

But the Vermont senator's victory in New Hampshire and good showing in Iowa mean he is being considered as a possible candidate for November's election.

He is financing his campaign by asking thousands of supporters for relatively small amounts of money.

He made $9 million in the hours after Iowa and New Hampshire.

Tad Devine, senior advisor to Sanders said:'We're in uncharted territory here. No one has ever done what we're doing, raising almost every dollar from small-dollar contributions. So we're hopeful and we're optimistic that we'll have a lot of resources, but we have the resources in now to compete nationally.'

Sanders' average donation is around $27 compared with the legal maximum of $2,700.
