Hong Kong activist Joshua Wong: 'We will continue our battle until the day we have democracy'

In Hong Kong, protesters are prepared to take to the streets on July 1, the day of Hong Kong's handover from the UK to China, to protest a controversial bill that would allow extradition from Hong Kong to mainland China. Joshua Wong is one of the leaders of the protest movement, and he spoke to The World's host, Marco Werman, about his experience advocating for Hong Kong's people.
