President Trump has made history, as he has become the first US president to attend America’s largest annual anti-abortion rally.
He addressed thousands of protesters at the March for Life near the US Capitol where his impeachment trial is ongoing.
Mr Trump said: “We’re here for a very simple reason: to defend the right of every child born and unborn to fullfil their God-given potential.”
The annual demonstration first began in 1974 – a year after the US Supreme Court legalised abortion in Roe v Wade.
Until now no president had ever attended the march, which takes place just steps from the White House, though previous Republican presidents, including George W Bush and Ronald Reagan, have addressed the group remotely.
Mike Pence became the first sitting vice-president to attend the rally in 2017.
Mr Trump’s appearance at the 47th March for Life delighted protesters.
Voters who support limiting abortion make up a key constituency for Mr Trump, who is seeking their support at the polls again in the 2020 election.
On Friday, marchers in Washington shouted “four more years” and “we love you”.
