Story highlights The Democratic Party platform will be officially voted on at the Democratic National Convention next month

A third of the seats on the Platform Committee were held by Sanders supporters

Washington (CNN) Hillary Clinton's campaign on Saturday praised a draft of the Democratic Party's 2016 platform, which reflects several of the progressive issues voiced by her primary challenger, Vermont Sen. Bernie Sanders.

Calling the platform "the most ambitious and progressive platform our party has ever seen," Maya Harris, a Clinton policy adviser, praised the platform's call for a repeal of the Hyde Amendment, which bans the use of federal funds to pay for abortions in most circumstances, and expanding Social Security.

Most notably, Harris hails the support for people to earn at least $15 an hour -- a key issue for Sanders, who has advocated for a $15 federal minimum wage while Clinton has stopped at $12 and favored state efforts to raise their minimum wages beyond that figure.

Other nods to the party's progressive wing include an emphasis on increasing clean energy production, curbing "Wall Street greed" and hiking taxes on multi-millionaires.

The platform also calls for a review of past trade agreements -- notably the Trans-Pacific Partnership pushed by President Barack Obama and formerly supported by Clinton until she came out last year against it under heavy pressure from progressives.
