Democrat debate viewers are wondering what was drawn on Tom Steyer’s hand.

As the billionaire would raise his left hand, cameras captured an odd symbol in pen or marker:

A large cross, surrounded by four others, was on the candidate’s appendage during the Des Moines event.

Former Obama aide Tommy Vietor wondered if Steyer was playing a game.

“Did Steyer play tick tack toe on his hand?”

Others caught it, too:

Some noted it resembled the Jerusalem Cross.
