I think he has worn one. IIRC, he was wearing one during one of his prime time press conferences. My mom pointed it out to me.
Haven’t found anything other than someone asking in ‘08 why he’s not wearing one anymore... Though while looking for something to confirm this I came across this about Gibbs at Huffpo—

Gibbs sure looks stoned in that photo. Probably a pot head. I can’t believe Obama has the guts to ever wear an earing though I’m sure he’s like one. I can’t take earing guys seriously
