Python json library not parsing valid json string?

I am trying to parse json obtained from this api call: https://poloniex.com/public?command=returnTicker

But when I run the commands:

    print site_name
    site = urllib2.Request(site_name)

    response=urllib2.urlopen(site_name) 

    print response.read()

    t= json.loads(response.read())

I get:

https://poloniex.com/public?command=returnTicker
{"BTC_BCN":  ... (rest of json response)
ValueError: No JSON object could be decoded

I have validated the resulting json object using www.jsonlint.com and it is valid. What am I doing wrong?

if you print response.read(), then the next time you try to read from it you'll get an empty string.

Empty string is not a valid json string.
