President Trump has filed suit against the Democrats, particularly Rep. Elijah Cummings, to block a subpoena asking for information on his finances and tax returns.

According to CNBC:

President Donald Trump and his business filed suit against Democratic House Oversight Committee Chairman Elijah Cummings on Monday to block a subpoena sent last week seeking information about the president’s finances.

In the complaint filed in Washington, D.C., federal court Monday morning, Trump said that Democrats have “declared all-out political war” against him.

…

The subpoena requested a slew of financial documents and related materials from Trump, his trust, the Trump Organization, the Trump Corporation, Trump’s holdings company, the Trump Foundation and the Trump International Hotel in Washington. Mazars told the committee that it would not be able to comply with demands for those documents without a subpoena, according to Cummings.

Trump’s lawyer in the lawsuit, William Consovoy, said in a statement that the attempt by Cummings’ committee to “obtain years’ worth of confidential information from their accountants lacks any legitimate legislative purpose, is an abuse of power, and is just another example of overreach by the president’s political opponents.”

The president’s team has stated that they will not allow for the continued presidential harassment from Congress. The subpoena is directed at Mazars, an accounting firm that Trump used to prepare his financial statements.
