Google (NSDQ: GOOG) will renew some old acquaintances at the U.S. Department of Justice before its Motorola (NYSE: MMI) deal is allowed to pass. The company announced Wednesday that the government has asked for “more information” about certain aspects of the $12.5 million [sic, billion] deal, which would bring one of the leading Android smartphone vendors under Google’s wing.

This isn’t a deal killer, but it certainly throws up a roadblock in the way of Google acquiring Motorola Mobility. Anyone expecting a quick resolution is probably going to be waiting a bit.
