Excerpts of the President's News Conference
I expect we shall observe Christmas at the White House about as usual. My boy John is coming home from college. I think he will be home on Sunday morning. I expect the observance of the holidays will be about the same as usual. The only difference, which will be apparent to all of you, is that three of us will be present rather than four, as in the past. I expect Mr. and Mrs. Stearns will be at the White House at that time, and on Christmas eve I am expecting that the Choir of the First Congregational Church will sing at the north portico of the White House the same as they did last year.
