President Trump is expected to sign an executive order on religious liberty this Thursday--- which is the National Day of Prayer, senior White House sources confirmed Tuesday to Fox News.

An early draft of the order, leaked in February, would have established broad exemptions for people and groups to claim religious objections under strong language.

The new draft of the executive order is being tightly held, Politico reported. A person identified as an "influential conservative" by Politico who saw the text said it hasn't been dialed back much since the leak. “The language is very, very strong,” the source told Politico.

Progressive critics have argued the executive order would allow discrimination against the LGBT community at the federal level.

Vice President Pence has been a proponent of the plan, and his office has been reportedly pushing for it for months.

While governor of Indiana, Pence signed a similar state law on religious liberty that stirred up controversy across the country, but was seen as a legislative win and rallying cry for social conservatives.
