President Obama’s campaign manager, Jim Messina will be at Harvard University on Tuesday, hoping to urge Harvard students to help “pass the bill” or reelect the President or something. However, students and others opposed to the Tar Sands oil development and the Keystone XL pipeline are also planning to be there to greet him.

So if you’re in the Boston area, just hop on the Red Line, get off at Harvard Square and walk down to the Kirkland House, right across from the Kennedy School. Messina is scheduled to be at the Kirkland House Junior Common Room about 3:30 p.m. Here’s a map.
