President Donald Trump early Wednesday morning slammed the reverend at a National Cathedral prayer service for the inauguration who called on him to have mercy on transgender children and immigrant families.

Episcopal bishop Right Rev. Mariann Budde preached a message of unity and urged President Donald Trump to show “mercy” during a Jan. 21, interfaith prayer service.

Now that the glitz and excitement of inauguration weekend has come to an end, President Donald Trump has resumed his most cherished pastime: late-night grievance-posting on social media. The first target of his second term in office: the “so-called Bishop” who asked him to have mercy on immigrants and the LGBTQ+ community.
