Trump and Musk side by side at Thanksgiving dinner...Re-confirming "closest."

At U.S. President-elect Donald Trump's Thanksgiving dinner, Tesla CEO Elon Musk took a seat right next to Trump, reaffirming that he is his "closest neighbor."

If you look at the video taken by the dinner participant and posted on social media, Trump and Musk sat side by side at the Mar-a-Lago dinner hall, which is Trump's mansion, and next to it was his youngest son Barron and his wife Melania.

The video showed Trump tapping Musk on the back and Musk singing along with his arms raised as the YMCA song, which was Trump's campaign song, came out.

Local media said Musk's mother, Meido Mar-a-Lago, attended the dinner, and Trump and Musk walked around the table together and greeted the attendees.

Musk, who is considered the top contributor to Trump's election, has been treated like a family member since the presidential election, staying at Mar-a-Lago, where the transition team camp has been set up.
