It's notable that Sessions recommended RR firing 1 week after recusing.
To answer your question, I could not find any articles quickly that specifically stated RR advised Sessions to recuse. However, RR was already in DOJ and Sessions took advice from senior DOJ members. See paragraph from article.
In the March 2 press conference in which he announced his recusal, Sessions explained that he’d consulted with senior DOJ officials before making his decision. “I asked for their candid and honest opinion about what I should do about investigations, certain investigations, and my staff recommended recusal,” he said. “They said that since I had involvement with the campaign, I should not be involved in any campaign investigation. I have studied the rules and considered their comments and evaluation. I believe those recommendations are right and just.”
Hope this helps.
