The Right Rev. Mariann Budde, the spiritual leader of the Episcopal Diocese of Washington, has voiced concern about Donald Trump’s language and conduct for years.

Bishop Mariann Edgar Budde called on President Trump to have mercy on transgender children and immigrant families at a National Cathedral prayer service for the inauguration Tuesday, which went viral and prompted the president to call her “nasty in tone” and “not compelling or smart.

The Episcopal bishop of Washington spoke with NPR to discuss her sermon addressing President Trump and why she asked him to have mercy.
