A Senate committee report has accused PricewaterhouseCoopers (PwC) of attempting to cover up a scandal involving the leak of tax information. The report alleges that PwC hid key details from investigators about its partners marketing confidential drafts of tax laws to top U.S. firms. It also claims that PwC delayed reviewing the matter for years and seems incapable of making substantive reforms. The accusations stem from a second interim report by the Senate standing committee on finance and public administration, titled 'the cover up worsens the crime,' highlighting the firm's withholding of information regarding the conduct of its international partners.
