She went to breastfeed her child just minutes before Trump's rally in North Carolina on Wednesday.
The agent, responsible for event security, was found in a room designated for Secret Service work, accompanied by 2 family members, bypassing security protocols.
Secret Service spokesman Anthony Guglielmi stated that the incident did not affect the event but is under investigation.
The incident comes shortly after a would-be assassin shot Trump at a Pennsylvania rally in July, raising concerns over Secret Service preparedness.
