Vice President of the United States Mike Pence became the highest-ranking government official to ever address the annual March for Life rally in Washington, DC.

Pledging that the new administration would limit abortion access as much as possible in the US, Pence told a cherring crowd that "life is winning again in America".

He opened with a reference to the Declaration of Independence's right to "life, liberty, and the pursuit of happiness," saying the country had abandoned the first principle when the Supreme Court ruled in the 1973 Roe v. Wade decision that women had a constitutional right to an abortion.

The 44th annual March for Life brought thousands of antiabortion demonstrators to the National Mall.

What next for women's reproductive rights in America?

With Republicans now in control of the White House and Congress, the party has indicated that it plans to try to restrict them in the next four years.

On Monday, his third full day in office, President Donald Trump signed an executive order reinstating a gag order keeping American non-governmental organisations that receive federal funding from discussing abortion abroad.

Pence said Trump would name a nominee - who specifically opposes abortion rights - for the vacant Supreme Court seat next week who opposes abortion rights.
