When the king found Haman falling on the couch where Esther reclined, what did the attendants do to Haman?

Answer: Covered his face

The king thought Haman was assaulting the queen, and as soon as the words left his mouth, they covered Haman's face.

“Just as the king returned from the palace garden to the banquet hall, Haman was falling on the couch where Esther was reclining. The king exclaimed, “Would he actually assault the queen while I am in the palace?” As soon as the words had left the king’s mouth, they covered Haman’s face.”— Esther 7:8 (BSB)
