PALM BEACH, Fla. (AP) — Two Republican senators who had said they did not recall President Donald Trump using a vulgarity to describe African countries backtracked Sunday and challenged other senators’ descriptions of the remark. Trump has been accused of using the word “shithole” to describe African countries during an Oval Office meeting Thursday with a bipartisan group of six senators in which the president also questioned the need to admit more Haitians to the U.S., according to people briefed on the conversation but not authorized to describe it publicly. Trump also said in the meeting that he would prefer immigrants from countries like Norway instead.
