PHILADELPHIA, the United States, July 28 (Xinhua) -- Former U.S. Secretary of State Hillary Clinton on Thursday formally accepted the Democratic Party's nomination for president and pledged more economic opportunities for Americans and "steady leadership."

"My primary mission as president will be to create more opportunities and more good jobs with rising wages right here in the United States from my first day in office to my last," Clinton said on the final day of the four-day Democratic National Convention.

"In my first 100 days, we will work with both parties to pass the biggest investment in new, good-paying jobs since World War II. Jobs in manufacturing, clean energy, technology and innovation, small business, and infrastructure," she added.

In an apparent move to woo disgruntled liberal supporters of Bernie Sanders, her former rival in the nomination race, Clinton also vowed to overturn the U.S. Supreme Court's 2010 Citizens United ruling that opened the door to unlimited donation in U.S. politics and to strengthen regulations of Wall Street banks and big corporations.

"I believe that our economy isn't working the way it should because our democracy isn't working the way it should," said the Democratic presidential nominee whose close ties to Wall Street had been scrutinized during the year-long campaign.

Meanwhile, by highlighting the looming global and national security threat facing the country, Clinton called for "steady leadership" and again questioned whether Donald Trump, the Republican presidential nominee, has the temperament to be commander-in-chief.

"Anyone reading the news can see the threats and turbulence we face. From Baghdad and Kabul, to Nice and Paris and Brussels, to San Bernardino and Orlando, we're dealing with determined enemies that must be defeated," she said. "No wonder people are anxious and looking for reassurance. Looking for steady leadership."
