Bernie Sanders to join insulin caravan to Windsor, Ont.

Bernie Sanders will join the next caravan to Canada for Americans to purchase insulin. 

Sanders announced Thursday he plans to come to Windsor, Ont. through Detroit, Mich. to "spotlight greed" existing in the American healthcare industry. 

He joins people with Type 1 diabetes who have been coming to Canada to purchase insulin — the drug costs about $30 in Canada, compared to about $300 in the United States.

"We can't wait for drug companies to lower prices," tweeted Sanders. "Americans need relief now."

Not the first time Sanders has taken a stand

Sanders is no stranger to coming with Americans to Canada to purchase medication. In 1999, Sanders joined women with breast cancer in crossing the border.
