Hillary Clinton kicked off her second presidential campaign Saturday on New York City's Roosevelt Island in a park where there are absolutely "no ceilings."

Thousands of supporters gathered at Saturday's rally as Clinton hit points on major issues for her first big campaign event for the 2016 race, according to MSNBC.

"I may not be the youngest candidate in this race, but I will be the youngest woman president in the history of the United States," the former secretary of state said. "And, the first grandmother as well."

Clinton sent a populist message as she promised to fight for equal pay for women, ban discrimination against the LGBT community and to focus more on early education and childcare.

"I'm not running for some Americans, but for all Americans," Clinton said.

New York City Public Advocate Letitia James supports Clinton because she has a long record of social justice, according to Mashable.

"We need more women in politics," James said. "She wants to make sure more people have access to the ballot, and that's why I am here."

Clinton showed videos of her political record ahead of the rally highlighting her women's rights work as first lady and her work with the Children's Defense Fund.

"I've spent my life fighting for children, families and our country, and I'm not stopping now," she said on Saturday.

The former first lady slammed the Republican Party's 2016 presidential candidates in her speech as well.

"They shame and blame women rather than respect our right to make our own decisions. ... And they turn their backs on gay people who love each other," she said.

"There may be some new voices in the presidential Republican choir, but they are all singing the same old song, a song called 'Yesterday.'"

Clinton is viewed as the most likely head of the Democratic race. Will she win the big ticket?
