An Army veteran spent 2 years looking for his missing son in the desert. Now, he's running for Congress.

• David Robinson, who's spent the last two years searching for his son, is running for US Congress.
• The veteran hopes his campaign will add momentum to the search for Daniel, who disappeared in July 2021.
• For months, Robinson traveled across the US to search personally for Daniel in the Arizona desert.

Every fortnight or so, David Robinson starts his YouTube livestream, upbeat and all smiles.

"When the lights and camera turn off, I will be here," he rumbles in one of his intros. The Arizona desert appears on the screen. "When the interests and conversations fade, I will be here."
