WEATHERLY, Pa. (AP) — Mitt Romney on Saturday tried to refocus his bus tour on middle-class economic issues as he visited a Pennsylvania foundry a day after President Barack Obama’s new immigration policy consumed the campaign debate.

“I think we have to have a very careful review of who’s giving a fair shot to the American people,” Romney told a crowd of several hundred packed into a warehouse at Weatherly Casting and Machine Co., next to the train tracks that run through this town about 90 miles northwest of Philadelphia.
