Ivanka Trump, the daughter of Republican presidential candidate Donald Trump, is being provided Secret Service protection, an official said Monday.

The protection started Monday and was first reported by NBC News. A Secret Service spokesperson confirmed to TIME that Ivanka is the first of Trump’s children to get protection, but referred questions about why the protection was granted to the Trump campaign.

The Secret Service declined to reveal Ivanka’s code name, though candidates and their family members usually have code names that begin with the same letter; Trump’s code name set is “Mogul.”

Donald Trump started receiving Secret Service protection during the 2016 primary contest.

Secret Service protection for presidential and vice presidential candidates dates back to 1968. After Robert Kennedy was assassinated, protection for candidates and their spouses became standard practice.
