HARRISBURG - President Barack Obama is coming to Pennsylvania for the second time this year, this time as part of a two-state campaign swing.
The Obama campaign said his two-day bus tour will wrap up in Pittsburgh on Friday after a tour through northern Ohio.
In Pittsburgh, Obama will speak at Carnegie Mellon University's campus. The campaign says he'll focus on economic themes.
The visit coincides with the Obama's campaign release of a new TV ad in Pennsylvania this week that criticizes Republican rival Mitt Romney's economic philosophies.
It will be the president's first bus tour of the 2012 campaign. He last visited Pennsylvania in a trip to Philadelphia last month.
Romney took a bus tour of his own through Ohio and Pennsylvania last month.
