U.S. President Donald Trump sued on Monday to block a subpoena issued by the Democratic chairman of the U.S. House Oversight Committee that sought information about his personal and business finances.
The suit, the first salvo in what promises to be an escalating legal battle over efforts to investigate Trump by the Democratic-controlled U.S. Congress, alleged Democrats have launched "all-out political war" on Trump and subpoenas "are their weapon of choice."
The committee's subpoena had sought eight years of documents from Mazars USA, an accounting firm long used by Trump to prepare financial statements, related to its investigation of allegations Trump inflated or deflated financial statements for potentially improper purposes.
