Facebook CEO Mark Zuckerberg is expected to meet with some lawmakers Monday, his latest maneuver to prepare for hearings in front of three congressional committees this week, Reuters reports.

Why it matters: Last week Zuckerberg and Facebook COO Sheryl Sandberg worked the media, doing roughly a dozen interviews collectively. As Zuckerberg heads into trial mode this week, he’s expected to keep a low media profile and instead focus his efforts chiefly on Capitol Hill.

What he's doing:

1. Zuckerberg will hold meetings with some U.S. lawmakers ahead of his hearings on Monday, sources tell Reuters. The meetings are said to include some members of the committees that will be questioning Zuckerberg later in the week.
2. Facebook has hired a team of experts, including a former special assistant to President George W. Bush, to give Zuckerberg "a crash course in humility and charm," The New York Times reports.
3. The company will notify users whose data may have been provided to Cambridge Analytica on Monday.
4. Facebook has been taking action on more third-party data vendors ahead of the testimony. It suspended data analytics firm CubeYou, after CNBC found that the organization used personality quizzes that were labeled as "non-profit academic research" to help advertisers target customers, a similar tactic to those used by Cambridge Analytica.

Be smart: Its camera-shy CEO has never testified before Congress and has no Washington experience. How well he satisfies lawmakers will shape whether talks about regulations turn out friendly or tough.
