A baby known widely on social media as “Bernie Baby” has died, reportedly of sudden infant death syndrome, at the age of 3.5 months.

Oliver Jack Carter Lomas appeared in numerous photos wearing a messy white wig and large glasses reminiscent of Democratic presidential candidate Bernie Sanders.

Oliver actually met his style inspiration in February, when his mother, Susan Lomas, brought him to a Sanders rally in Las Vegas.

The Independent Journal reported Tuesday that Oliver had died. His mother posted about his death and funeral arrangements on Facebook and Twitter.

Lomas was not immediately available for comment. Funeral service company Forest Lawn confirmed the details of Oliver's arrangements to The Huffington Post. Oliver’s aunt, Anastasia Lomas, commented on a Facebook meme featuring the baby that SIDS was the cause of death.
