Mark Zuckerberg's first stop on his 2017 tour of the US is Dallas, Texas.

The billionaire Facebook CEO helped plant fruits and vegetables in a community garden in the Oak Cliff neighborhood of Dallas on Martin Luther King Jr. Day, according to his Facebook page. He also met with computer science students from a local public high school.

Zuckerberg's main reason for being in Dallas is to testify on Tuesday in a $2 billion lawsuit that claims the Oculus VR company he acquired in 2014 was based on stolen technology. He and other key Oculus executives, including Palmer Luckey, will take the stand this week to defend the company against video game maker Zenimax.

Zuckerberg's personal goal for 2017 is to visit and meet people from every US state he hasn't visited yet, a statesman-like agenda that has sparked more speculation that he could be plotting to eventually run for public office.
