Friday’s March for Life will include an “historic” list of speakers calling for the overturn of the landmark Supreme Court case Roe v. Wade including top Trump aide Kellyanne Conway, New York Cardinal Timothy Dolan, Baltimore Raven Benjamin Watson and a former executive of Planned Parenthood.

The 44th march in Washington, expected to draw tens of thousands, is also expected to have the attention of the White House. Vice President Pence spoke at several marches while serving as an Indiana congressman but hasn’t indicated if he will attend or call in a statement.
