The highest-ranking woman in President Trump’s administration, Kellyanne Conway, will defend the sanctity of life and rally against abortion at the 43rd Annual March for Life — the world’s largest annual pro-life demonstration — in Washington, D.C., on Friday, Jan. 27.

White House press secretary Sean Spicer spoke about the administration’s involvement in the March for Life. “I know Kellyanne [Conway] is going to attend the event,” Spicer said in the second official White House press conference. “I think we’re still working through the details, but we’ll have further information about the president’s potential participation in that.”

“We are thrilled to have Kellyanne Conway speak at this year’s March for Life.”

Unrestricted abortion access was a key theme on which Hillary Clinton and her running mate Virginia Sen. Tim Kaine campaigned during the 2016 bid for the White House — and under the Trump administration the priorities on the issue are clear.

“We are thrilled to have Kellyanne Conway speak at this year’s March for Life. As the first female to run a successful presidential campaign and a steadfast advocate for life and family issues, Kellyanne beautifully embodies the 2017 March for Life’s theme, ‘The Power of One,'” said March for Life President Jeanne Mancini in a statement.

Conway, who served as Donald Trump’s unflappable campaign manager and senior adviser to the president-elect’s transition team, recently joined the White House as counselor to the president. A veteran pollster and political strategist, she played no small role in helping Trump win the White House.

To be sure, her presence at Friday’s rally will underscore the Trump administration’s pro-life commitment. On Monday, President Trump signed an executive order reinstating the Mexico City Policy, which defunds groups that promote abortions overseas, such as International Planned Parenthood. It does not, however, bar foreign aid for health care and humanitarian relief.

“President Trump’s immediate action to promote respect for all human life, including vulnerable unborn children abroad, as well as conscience rights, sends a strong signal about his administration’s pro-life priorities,” said Marjorie Dannenfelser, president of Susan B. Anthony List, a pro-life advocacy group, in an email to LifeNews.com.

Conway is a mom to four small children and the president and CEO of The Polling Company Inc./WomanTrend. At the March for Life rally on the National Mall, she will join Archbishop of New York Cardinal Timothy Dolan, former Planned Parenthood Director Abby Johnson (who is also the founder of “And Then There Were None”), Mexican Telenovela star Karyme Lozano, author and radio host Eric Metaxas, Bishop Vincent Matthews of the Church of God in Christ, who advocates for adoption in the African-American community, and others.

“It is our hope that this year’s March for Life will encourage each of us to seek and fulfill our unique mission to the best of our ability, because only in doing so we will collectively build a culture of life in the U.S. — a culture where abortion is unthinkable,” added Mancini in her statement.

“Tens of thousands of Americans are expected to travel to D.C. for this year’s March for Life, which seeks to promote the dignity of every human life and to stand against the greatest human rights violation of our time: abortion on demand,” read a March for Life press release.

The LifeSiteNews website said that 60 million babies have been aborted since 1973.

The pro-life gathering, with its unifying pro-life theme, stands in sharp contrast to last week’s March on Washington, where marchers — including Madonna, who told the crowd she had “thought an awful lot about blowing up the White House”— seemed to have a million messages, as an opinion piece in The Wall Street Journal noted. The Material Girl later walked back her comment.

Meanwhile, pro-life groups, including New Wave Feminists and Students for Life of America, were excluded from officially participating.

The March for Life is set to begin around 1:00 p.m. EST, following the conclusion of the rally.
