It’s said that the Twitter messages actually thumbed by President Barack Obama @BarackObama are signed `BO.’

The one this morning came from St. John’s, the church across Lafayette Park from the White House, where the first family went this morning on the chilly and partl;y cloudy day of the public inauguration ceremonies:

“I’m honored and grateful that we have a chance to finish what we started. Our work begins today. Let’s go. -bo”

The president and his family arrived at St. John’s at 8:35 am EST.

The service ended at 9:39.

BO tweeted at 9:25.
