Charles Ellicott Commentary Esther 2:22

"And the thing became known to Mordecai, who showed it unto Esther the queen; and Esther told the king [thereof] in Mordecai`s name." — Esther 2:22 (ASV)

And Esther certified the king thereof. —Doubtless by this means an increased influence was gained over the capricious mind of the king, an influence which before long served Esther in good stead.
