The French president was greeting the people waiting for him behind obstacles in the town of Tain-l'Hermitage after he visited a high school that's training students to work in hotels and restaurants. A movie of this incident was posted on Twitter.
Macron explained the episode as an"isolated act" in an interview with local newspaper Le Dauphine Libere.
Macron said he did not have specific concerns following the assault.
"I greeted the people who were by the man's side and made pictures with them. I continued and will continue. Nothing will prevent me," he said.
