President Donald Trump announced Wednesday that he will attend Friday’s March for Life, the annual gathering of antiabortion protesters commemorating the anniversary of Roe v. Wade, the Supreme Court’s landmark abortion decision on abortion.

While other U.S. presidents have addressed the annual rally by phone or sent video greetings, Trump would be the first to address the crowd in person.

His appearance was announced during the first week of the president’s impeachment trial in the U.S. Senate, and as his bond with groups opposing abortion grows stronger. Just a few days, ago the pro-life group SBA List and its affiliated super PAC announced it would spend $52 million to help the president’s reelection and work to protect the GOP’s Senate majority, Politico reported.

The rally, which includes several events before the actual march, will start at noon on the National Mall in Washington. After the rally, the march to the Supreme Court will begin about 1 p.m.

In 2017, shortly after Trump was sworn in, Mike Pence became the first vice president to address the march in person. Trump appeared via satellite TV at the 2017 March, thrilling a crowd that has become increasingly associated with the GOP. In 2018 left-leaning pro-lifers were heartbroken by Trump’s appearance there.

Last year, Trump and Pence gave unannounced addresses to the crowd and Trump addressed participants gathered at a smaller Rose Garden gathering. Conservative podcast host Ben Shapiro was also a star guest.

In her announcement that the president will speak, Jeanne Mancini, president of March for Life, praised the current administration’s record on abortion.

“From the appointment of pro-life judges and federal workers, to cutting taxpayer funding for abortions here and abroad, to calling for an end to late-term abortions, President Trump and his Administration have been consistent champions for life and their support for the March for Life has been unwavering,” she said.
