Christian humanitarian group World Relief published a letter in the Washington Post on Feb. 8 with signatures from 100 prominent evangelical leaders asking Trump to reassess his decision. Signatories included popular Christian authors Tim Keller, Max Lucado, and Ann Voskamp, as well as church leaders such as Bill Hybels, Eric Costanzo, and Eugene Cho. World Relief opened the letter to other pastors and church staff and this morning delivered it to the White House with more than 3,000 signatures from congregations in all 50 states.
