There has been news this morning that the US government is expected to file a lawsuit against Google, accusing the tech giant of maintaining an illegal monopoly over Internet searches and advertising.
The legal action would be among the most serious challenges to the size and power of a large American technology firm in a generation.
According to reports, the Department of Justice will accuse Google of being party to illegal agreements to lock out search engine competitors.
Among those is an alleged agreement with Apple, which sees Google pay its rival billions of dollars to use Google as the default search engine on iPhones.
Brent Kendall is a legal affairs reporter for the Wall Street Journal in Washington.
