Feedparser.parse() 'SSL: CERTIFICATE_VERIFY_FAILED'

I'm having this SSL issue with feedparser parsing an HTTPS RSS feed, I don't really know what to do as I can't find any documentation on this error when it comes to feedparser:

>>> import feedparser>>> feed = feedparser.parse(rss)>>> feed{'feed': {}, 'bozo': 1, 'bozo_exception': URLError(SSLError(1, u'[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:581)'),), 'entries': []}>>> feed["items"][]>>>
