I expect that Senator Collins is likely winging her way back home, perhaps with another stop. We now know the trip, according to a Kennebec Journal piece was a 9 day trip or almost a third of the August Senate recess:
"U.S. Sen. Susan Collins, currently on a nine-day trip to the Middle East, has scheduled a number of community celebrations and a public forum when she returns, deputy press secretary Ian Swanberg said."
Collins should have stayed home. The priority should have been, without doubt, was to work hard on health care for Maine citizens at this crucial time. Collins recognized the need in the past in this video featured on Collins Watch.
Senator Collins talked about her desire for Congress to set aside two or three months to work on "virtually nothing but health care." I guess August in Augusta just is not one of those months.
