“Something was said which drew from General Taylor the expression of views which greatly surprised me. They were to the effect that California and Oregon were too distant to become members of the Union, and it would be better for them to be an independent government. He said that our people would inhabit them and repeated that it would be better for them to form an independent government for themselves. These are alarming opinions to be entertained by the President of the United States.”
An excerpt from James K. Polk’s diary entry of Monday, March 5, 1849. Polk is relating a conversation between himself, President Zachary Taylor, W.W. Seaton (the Mayor of Washington D.C.), and Robert Winthrop (former Speaker of the House of Representatives) conducted during a carriage ride after Taylor’s inauguration.
