Timeline: LifeSiteNews

Archbishop Carlo Maria Viganò, declared excommunicated for schism in 2024, posted a critique on X of Leo XIV's 25 September address at the Élysée Palace, which LifeSiteNews republished. He objected to the speech's favourable references to Enlightenment-era thinkers in connection with human rights and to its treatment of France's motto liberté, égalité, fraternité.

On the feast of the Canadian Martyrs, the SSPX's national pilgrimage to the Martyrs' Shrine in Midland, Ontario, could not enter the shrine church or venerate the relics there, after the Archdiocese of Toronto under Cardinal Frank Leo barred SSPX groups from diocesan sites following the 1 July consecrations; Mass was celebrated in a nearby park. In an update dated 6 October, the society's Canadian district superior, Fr. Yves Le Roux, asked the faithful to accept the decision without bitterness, writing "we fully submit to this decision of the Cardinal." The society put attendance at about 300.

At Vespers with French clergy and religious in Notre-Dame Cathedral on the first day of his visit to France, Leo XIV urged that the liturgy be celebrated "with dignity and decorum" (InfoVaticana's rendering) and asked his listeners to place communion with the Successor of Peter and with the Church above personal preferences for the sake of unity. LifeSiteNews suggested the passage could be read as a reference to the SSPX and the traditional Latin Mass; an UnHerd column later argued that Leo treats the old rite as a personal preference rather than a source of renewal.

On the day the Vatican published A Journey of Hope, its note marking sixty years of Nostra Aetate, Bishop Joseph Strickland wrote on X that the statement "must be rejected and repudiated by all who hold Jesus Christ and His Church as the only way to the Father," objecting to a passage on proselytism. LifeSiteNews reported his view that the note "can give rise to grave confusion"; The Letters from Leo, a newsletter covering the pontificate, pointed out that the note says dialogue must avoid relativism and syncretism.

LifeSiteNews announced that, after a board vote, co-founder John-Henry Westen was no longer CEO and editor-in-chief. On July 18, 2025, CatholicVote reported that he had been reinstated as president and CEO, with the board's decision described as subject to an administrative review. In September 2025 LifeSiteNews said an outside investigation had cleared him of wrongdoing.

At the Rome Life Forum, Strickland read from a letter by an unnamed friend that, according to OSV News, called Pope Francis a usurper of Peter's chair, and himself accused the pope of backing an attack on the sacred.

YouTube terminated the LifeSiteNews channel, which had more than 300,000 subscribers, citing repeated violations of its COVID-19 misinformation policy. LifeSiteNews said it was not told which video triggered the final strike and continued posting video on Rumble.

An open letter from Archbishop Viganò dated 7 June 2020 and published by LifeSiteNews framed the pandemic and U.S. protests as part of a spiritual battle and described a 'deep state' and a 'deep church'. President Trump praised it on Twitter on 10 June.

LifeSiteNews began in 1997 as a news service connected to the Canadian pro-life lobbying group Campaign Life Coalition, with Steve Jalsevac and John-Henry Westen as founding staff. Westen served as editor-in-chief from the start.
