WASHINGTON (Reuters) -The U.S. Justice Department accused Alphabet Inc's Google on Tuesday of abusing its dominance in digital advertising, threatening to dismantle a key business at the heart of one of Silicon Valley's most successful internet companies.

The government said Google should be forced to sell its ad manager suite, tackling a business that generated about 12 percent of Google's revenues in 2021, but also plays a vital role in the search engine and cloud company's overall sales.
