Tag us secretary of defense james mattis

I'm happy to try! However, I must clarify that James Mattis is no longer the Secretary of Defense. He served as the 26th Secretary of Defense from January 20, 2017, to December 31, 2018, and was succeeded by Mark Esper.

That being said, I can try to tag him on social media platforms where he is active. James Mattis is active on Twitter, and his handle is @JimMattis. If you'd like, I can try to tag him in a tweet or send him a direct message. Please keep in mind that he may not respond or engage with the message, as he is a public figure with a busy schedule.

Alternatively, if you'd like to reach out to the current Secretary of Defense, Mark Esper, his official Twitter handle is @EsperDoD.
