“Although President Lincoln officially ended slavery with the Emancipation Proclamation on Jan. 1, 1863, it wasn’t until two years later, on June 19, 1865, that the slaves of Galveston, Texas, got the news . . .”
Even Ann should know the EP didn’t officially end slavery.
The United States clung to slavery well after the disaster at Appomattox; well after June 19.
The EP applied only to Confederate States.
There were several slaves states in the union that were unaffected.
