New York: Even by his standards, President Donald Trump unleashed an unusual number of tweets on Christmas Eve in the US.

As most families were enjoying the holiday season, Trump barked out his grievances. The border wall, his unpopular decision to withdraw troops from Syria and why the Federal Reserve is like a powerful golfer who can't putt were all addressed in ten tweets sent within three hours on Monday.

Then, one tweet seemed to explain Trump's behaviour. The President is alone in the White House.

"Poor me," he tweeted.
