(Bridgewater, N.J./WASHINGTON) — President Donald Trump decried on Thursday the removal of monuments to the pro-slavery Civil War Confederacy, echoing white nationalists and drawing stinging rebukes from fellow Republicans in a controversy that has inflamed racial tensions. Trump has alienated Republicans, corporate leaders and U.S. allies, rattled markets and prompted speculation about possible White House resignations with his comments since Saturday’s violence in Charlottesville, Virginia, which came in the aftermath of a white nationalist protest against the removal of a Confederate statue. Republican Senator Bob Corker, chairman of the Senate Foreign Relations Committee, questioned Trump‘s capacity to govern. “The president has not yet been able to demonstrate the ability or the competence that he needs to be successful,” said Corker, who Trump had considered for the job of secretary of state.
