By Dustin Volz WASHINGTON (Reuters) - Six Democratic U.S. senators on Tuesday asked embattled Yahoo CEO Marissa Mayer for more information about the internet company's investigation into a hack that compromised data related to 500 million user accounts. "That means millions of Americans’ data may have been compromised for two years," the senators wrote in a joint letter addressed to Mayer. "This is unacceptable." Yahoo has faced pointed questions about exactly when it knew about the 2014 cyber attack that exposed the email credentials of users, a critical issue for the company as it seeks to prevent the breach from affecting a pending takeover of its core business by Verizon Inc .
